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withdrawn from the ledger.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Accounts with stake force withdrawn greater than ED: 59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Accounts with stake force withdrawn greater than ED: 48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

## 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.
- [x] Investigate kusama accounts with balance between 0 and ED.
- [x] Permissionless call to release lock.
- [x] Migration of consumer (dec) and provider (inc) for direct stakers.
- [x] force unstake if hold cannot be applied to all stake.
- [x] Fix try state checks (it thinks nothing is staked for unmigrated
ledgers).
- [x] Bench `migrate_currency`.
- [x] Virtual Staker migration test.
- [x] Ensure total issuance is upto date when minting rewards.

Zombienet substrate tests PoC (using native provider).

cc: @emamihe @alvicsam

closes https://github.com/paritytech/polkadot-sdk/issues/6911

The changes from v0.10.3 are only related to dependencies version. This
should fix some failing CIs.

This PR also updates the Rust cache version in CI.

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

This PR provides the partial results of the `GetRecord` kademlia query.

This significantly improves the authority discovery records, from ~37
minutes to ~2/3 minutes.
In contrast, libp2p discovers authority records in around ~10 minutes. 

The authority discovery was slow because litep2p provided the records
only after the Kademlia query was completed. A normal Kademlia query
completes in around 40 seconds to a few minutes.
In this PR, partial records are provided as soon as they are discovered
from the network.

### Testing Done

Started a node in Kusama with `--validator` and litep2p backend.
The node discovered 996/1000 authority records in ~ 1 minute 45 seconds.
