This PR introduces BlockNumberProvider config for pallet society.
closes part of https://github.com/paritytech/polkadot-sdk/issues/6297

- Closes https://github.com/paritytech/license-scanner/issues/44
- Silent because only comments are changed in the crates.

## What's inside

First, we change the file traversal mechanism from shell globbing to
walking through files which happens inside the `license-scanner` - so it
has knowledge about directory structure and can correlate files with
corresponding Cargo manifest.

Next, added `MIT-0` and `Unlicense` to the allowed list of licenses.
`Unlicense` appears only once across {Substrate,Cumulus,Polkadot} - in
`penpal-runtime`.

Finally, updated headers in files that do not match the corresponding
manifest license.

Apply some fixes to properly estimate ethereum tx fees:

- Set the `extension_weight` on the dispatch_info to properly calculate
the fee with pallet_transaction_payment
- Expose the gas_price through Runtime API, just in case we decide to
tweak the value in future updates, it should be read from the chain
rather than be a shared constant exposed by the crate
- add a `evm_gas_to_fee` utility function to properly convert gas to
substrate fee
- Fix some minor gas encoding for edge cases

This PR is centered around a main fix regarding the base deposit and a
bunch of drive by or related fixtures that make sense to resolve in one
go. It could be broken down more but I am constantly rebasing this PR
and would appreciate getting those fixes in as-one.

**This adds a multi block migration to Westend AssetHub that wipes the
pallet state clean. This is necessary because of the changes to the
`ContractInfo` storage item. It will not delete the child storage
though. This will leave a tiny bit of garbage behind but won't cause any
problems. They will just be orphaned.**

## Record the deposit for immutable data into the `storage_base_deposit`

The `storage_base_deposit` are all the deposit a contract has to pay for
existing. It included the deposit for its own metadata and a deposit
proportional (< 1.0x) to the size of its code. However, the immutable
code size was not recorded there. This would lead to the situation where
on terminate this portion wouldn't be refunded staying locked into the
contract. It would also make the calculation of the deposit changes on
`set_code_hash` more complicated when it updates the immutable data (to
be done in #6985). Reason is because it didn't know how much was payed
before since the storage prices could have changed in the mean time.

In order for this solution to work I needed to delay the deposit
calculation for a new contract for after the contract is done executing
is constructor as only then we know the immutable data size. Before, we
just charged this eagerly in `charge_instantiate` before we execute the
constructor. Now, we merely send the ED as free balance before the
constructor in order to create the account. After the constructor is
done we calculate the contract base deposit and charge it. This will
make `set_code_hash` much easier to implement.

As a side effect it is now legal to call `set_immutable_data` multiple
times per constructor (even though I see no reason to do so). It simply
overrides the immutable data with the new value. The deposit accounting
will be done after the constructor returns (as mentioned above) instead
of when setting the immutable data.

## Don't pre-charge for reading immutable data

I noticed that we were pre-charging weight for the max allowable
immutable data when reading those values and then refunding after read.
This is not necessary as we know its length without reading the storage
as we store it out of band in contract metadata. This makes reading it
free. Less pre-charging less problems.

## Remove delegate locking

Fixes #7092

This is also in the spirit of making #6985 easier to implement. The
locking complicates `set_code_hash` as we might need to block settings
the code hash when locks exist. Check #7092 for further rationale.

## Enforce "no terminate in constructor" eagerly

We used to enforce this rule after the contract execution returned. Now
we error out early in the host call. This makes it easier to be sure to
argue that a contract info still exists (wasn't terminated) when a
constructor successfully returns. All around this his just much simpler
than dealing this check.

## Moved refcount functions to `CodeInfo`

They never really made sense to exist on `Stack`. But now with the
locking gone this makes even less sense. The refcount is stored inside
`CodeInfo` to lets just move them there.

## Set `CodeHashLockupDepositPercent` for test runtime

The test runtime was setting `CodeHashLockupDepositPercent` to zero.
This was trivializing many code paths and excluded them from testing. I
set it to `30%` which is our default value and fixed up all the tests
that broke. This should give us confidence that the lockup doeposit
collections properly works.

## Reworked the `MockExecutable` to have both a `deploy` and a `call`
entry point

This type used for testing could only have either entry points but not
both. In order to fix the `immutable_data_set_overrides` I needed to a
new function `add_both` to `MockExecutable` that allows to have both
entry points. Make sure to make use of it in the future :)

Related to https://github.com/paritytech/polkadot-sdk/issues/7400 and
https://github.com/paritytech/polkadot-sdk/pull/7417

We need this in order to be able to update `parity-scale-codec` to the
latest version after it's released. That's because `parity-scale-codec`
added support for checking for duplicate indexes at compile time.

This PR changes the behavior of `instantiate` when the resulting
contract address already exists (because the caller tried to instantiate
the same contract with the same salt multiple times): Instead of
trapping the caller, return an error code.

Solidity allows `catch`ing this, which doesn't work if we are trapping
the caller. For example, the change makes the following snippet work:

```Solidity
try new Foo{salt: hex"00"}() returns (Foo) {
    // Instantiation was successful (contract address was free and constructor did not revert)
} catch {
    // This branch is expected to be taken if the instantiation failed because of a duplicate salt
}

This PR modifies `named_reserve()` in frame-balances to use checked math
instead of defensive saturating math.

The use of saturating math relies on the assumption that the sum of the
values will always fit in `u128::MAX`. However, there is nothing
preventing the implementing pallet from passing a larger value which
overflows. This can happen if the implementing pallet does not validate
user input and instead relies on `named_reserve()` to return an error
(this saves an additional read)

This is not a security concern, as the method will subsequently return
an error thanks to `<Self as ReservableCurrency<_>>::reserve(who,
value)?;`. However, the `defensive_saturating_add` will panic in
`--all-features`, creating false positive crashes in fuzzing operations.

Closes #216.

This PR allows pallets to define a `view_functions` impl like so:

```rust
#[pallet::view_functions]
impl<T: Config> Pallet<T>
where
	T::AccountId: From<SomeType1> + SomeAssociation1,
{
	/// Query value no args.
	pub fn get_value() -> Option<u32> {
		SomeValue::<T>::get()
	}

	/// Query value with args.
	pub fn get_value_with_arg(key: u32) -> Option<u32> {
		SomeMap::<T>::get(key)
	}
}
```
### `QueryId`

Each view function is uniquely identified by a `QueryId`, which for this
implementation is generated by:

```twox_128(pallet_name) ++ twox_128("fn_name(fnarg_types) -> return_ty")```

The prefix `twox_128(pallet_name)` is the same as the storage prefix for pallets and take into account multiple instances of the same pallet.

The suffix is generated from the fn type signature so is guaranteed to be unique for that pallet impl. For one of the view fns in the example above it would be `twox_128("get_value_with_arg(u32) -> Option<u32>")`. It is a known limitation that only the type names themselves are taken into account: in the case of type aliases the signature may have the same underlying types but a different id; for generics the concrete types may be different but the signatures will remain the same.

The existing Runtime `Call` dispatchables are addressed by their concatenated indices `pallet_index ++ call_index`, and the dispatching is handled by the SCALE decoding of the `RuntimeCallEnum::PalletVariant(PalletCallEnum::dispatchable_variant(payload))`. For `view_functions` the runtime/pallet generated enum structure is replaced by implementing the `DispatchQuery` trait on the outer (runtime) scope, dispatching to a pallet based on the id prefix, and the inner (pallet) scope dispatching to the specific function based on the id suffix.

Future implementations could also modify/extend this scheme and routing to pallet agnostic queries.

### Executing externally

These view functions can be executed externally via the system runtime api:

```rust
pub trait ViewFunctionsApi<QueryId, Query, QueryResult, Error> where
	QueryId: codec::Codec,
	Query: codec::Codec,
	QueryResult: codec::Codec,
	Error: codec::Codec,
{
	/// Execute a view function query.
fn execute_query(query_id: QueryId, query: Query) -> Result<QueryResult,
Error>;
}
```
### `XCQ`
Currently there is work going on by @xlc to implement [`XCQ`](https://github.com/open-web3-stack/XCQ/) which may eventually supersede this work.

It may be that we still need the fixed function local query dispatching in addition to XCQ, in the same way that we have chain specific runtime dispatchables and XCM.

I have kept this in mind and the high level query API is agnostic to the underlying query dispatch and execution. I am just providing the implementation for the `view_function` definition.

### Metadata
Currently I am utilizing the `custom` section of the frame metadata, to avoid modifying the official metadata format until this is standardized.

### vs `runtime_api`
There are similarities with `runtime_apis`, some differences being:
- queries can be defined directly on pallets, so no need for boilerplate declarations and implementations
- no versioning, the `QueryId` will change if the signature changes. 
- possibility for queries to be executed from smart contracts (see below)

### Calling from contracts
Future work would be to add `weight` annotations to the view function queries, and a host function to `pallet_contracts` to allow executing these queries from contracts.

### TODO

- [x] Consistent naming (view functions pallet impl, queries, high level api?)
- [ ] End to end tests via `runtime_api`
- [ ] UI tests
- [x] Mertadata tests
- [ ] Docs

This PR changes how we call runtime API methods with more than 6
arguments: They are no longer spilled to the stack but packed into
registers instead. Pointers are 32 bit wide so we can pack two of them
into a single 64 bit register. Since we mostly pass pointers, this
technique effectively increases the number of arguments we can pass
using the available registers.

To make this work for `instantiate` too we now pass the code hash and
the call data in the same buffer, akin to how the `create` family
opcodes work in the EVM. The code hash is fixed in size, implying the
start of the constructor call data.

# Derived Dev Accounts

Resolves https://github.com/paritytech/polkadot-sdk/issues/6040

## Description
This update introduces support for creating an arbitrary number of
developer accounts at the genesis block based on a specified derivation
path. This functionality is gated by the runtime-benchmarks feature,
ensuring it is only enabled during benchmarking scenarios.

### Key Features
- Arbitrary Dev Accounts at Genesis: Developers can now specify any
number of accounts to be generated at genesis using a hard derivation
path.

- Default Derivation Path: If no derivation path is provided (i.e., when
`Option<dev_accounts: (..., None)>` is set to `Some` at genesis), the
system will default to the path `//Sender//{}`.

- No Impact on Total Token Issuance: Developer accounts are excluded
from the total issuance of the token supply at genesis, ensuring they do
not affect the overall balance or token distribution.

Migrate staking currency from `traits::LockableCurrency` to
`traits::fungible::holds`.

Resolves part of https://github.com/paritytech/polkadot-sdk/issues/226.

## Changes
### Nomination Pool
TransferStake is now incompatible with fungible migration as old pools
were not meant to have additional ED. Since they are anyways deprecated,
removed its usage from all test runtimes.

### Staking
- Config: `Currency` becomes of type `Fungible` while `OldCurrency` is
the `LockableCurrency` used before.
- Lazy migration of accounts. Any ledger update will create a new hold
with no extra reads/writes. A permissionless extrinsic
`migrate_currency()` releases the old `lock` along with some
housekeeping.
- Staking now requires ED to be left free. It also adds no consumer to
staking accounts.
- If hold cannot be applied to all stake, the un-holdable part is force
withdrawn from the ledger.

### Delegated Staking
The pallet does not add provider for agents anymore.

## Migration stats
### Polkadot
Total accounts that can be migrated: 59564
Accounts failing to migrate: 0
Accounts with stake force withdrawn greater than ED: 59
Total force withdrawal: 29591.26 DOT

### Kusama
Total accounts that can be migrated: 26311
Accounts failing to migrate: 0
Accounts with stake force withdrawn greater than ED: 48
Total force withdrawal: 1036.05 KSM


[Full logs here](https://hackmd.io/@ak0n/BklDuFra0).

## Note about locks (freeze) vs holds
With locks or freezes, staking could use total balance of an account.
But with holds, the account needs to be left with at least Existential
Deposit in free balance. This would also affect nomination pools which
till now has been able to stake all funds contributed to it. An
alternate version of this PR is
https://github.com/paritytech/polkadot-sdk/pull/5658 where staking
pallet does not add any provider, but means pools and delegated-staking
pallet has to provide for these accounts and makes the end to end logic
(of provider and consumer ref) lot less intuitive and prone to bug.

This PR now introduces requirement for stakers to maintain ED in their
free balance. This helps with removing the bug prone incrementing and
decrementing of consumers and providers.

## TODO
- [x] Test: Vesting + governance locked funds can be staked.
- [ ] can `Call::restore_ledger` be removed? @gpestana 
- [x] Ensure unclaimed withdrawals is not affected by no provider for
pool accounts.

Closes #3149 

## Description

This PR introduces `pallet-asset-rewards`, which allows accounts to be
rewarded for freezing `fungible` tokens. The motivation for creating
this pallet is to allow incentivising LPs.

See the pallet docs for more info about the pallet.

## Runtime changes

The pallet has been added to
- `asset-hub-rococo`
- `asset-hub-westend`

The `NativeAndAssets` `fungibles` Union did not contain `PoolAssets`, so
it has been renamed `NativeAndNonPoolAssets`

A new `fungibles` Union `NativeAndAllAssets` was created to encompass
all assets and the native token.

## TODO
- [x] Emulation tests
- [x] Fill in Freeze logic (blocked
https://github.com/paritytech/polkadot-sdk/issues/3342) and re-run
benchmarks
