* implement max_values + storages info

* some formatting + doc

* rename StoragesInfo -> PalletStorageInfo

* merge both StorageInfoTrait and PalletStorageInfo

I think it is more future proof. In the future some storage could make
use of multiple prefix. Like one to store how much value has been
inserted, etc...

* Update frame/support/procedural/src/storage/parse.rs

* Fix max_size using hasher information

hasher now expose `max_len` which allows to computes their maximum len.
For hasher without concatenation, it is the size of the hash part,
for hasher with concatenation, it is the size of the hash part + max
encoded len of the key.

* fix tests

* fix ui tests

* Extends ChildStateBackend and ChildStateAPI with ReadProofs

read proof can be generated from a full client via an rpc call.

* Remove grandpa StoredPendingChange shim

* Unused import

* emit a custom section from impl_runtime_apis!

This change emits a custom section from the impl_runtime_apis! proc macro.

Each implemented API will result to emitting a link section `runtime_apis`.
During linking all sections with this name will be concatenated and
placed into the final wasm binary under the same name.

* Introduce `runtime_version` proc macro

This macro takes an existing `RuntimeVersion` const declaration, parses
it and emits the version information in form of a linking section.
Ultimately such a linking section will result into a custom wasm
section.

* Parse custom wasm section for runtime version

* Switch to proper Rust intra-doc link

* Don't remove addresses from known_external_addresses

* Remove `remove`

We need this in order to be able to assemble more fine grained host
function sets.

E.g. we don't want to use `SubstrateHostFunctions` for PVF. We would
better whitelist certain host functions. However, we cannot do that
because we cannot refer to the `Allocator` runtime interface.

I have not been able to find the reason why it wasn't made `pub` in the
first place, but do not see any reason why not to.

* Update pallet macro migrations.

* Revert dispatchable call visibility changes.

* Replace overflow/underflow in token error.

Before we required these trait bounds because of some bug in rustc, but
now as this bug is fixed they can be removed.

* requiring users to maintain an unchecked invariant is unsafe

* relax trait restrictions on BoundedVec<T, S>

A normal `Vec<T>` can do many things without any particular trait
bounds on `T`. This commit relaxes the bounds on `BoundedVec<T, S>`
to give it similar capabilities.

* contracts: Add default implementation for Executable::occupied_storage()

* contracts: Refactor the exec module

* Let runtime specify the backing type of the call stack

This removes the need for a runtime check of the specified
`MaxDepth`. We can now garantuee that we don't need to
allocate when a new call frame is pushed.

* Fix doc typo
