## Polkadot upgrade 2503
In this PR, we upgrade form Polkadot SDK 2412 to Polkadot SDK 2503. In
order to upgrade the SDK we need to upgrade some dependencies :
StorageHub and frontier simultaneously.
## What changes
### Trivial changes
* https://github.com/paritytech/polkadot-sdk/pull/7634 -> The new trait
is required in all the pallets using scale encoding.
* https://github.com/paritytech/polkadot-sdk/pull/7043 -> Remove
deprecated `sp-std` and replace with `alloc` or `core`.
* https://github.com/paritytech/polkadot-sdk/pull/6140 -> Accurate
weight reclaim with frame_system::WeightReclaim
### Breaking changes
* https://github.com/paritytech/polkadot-sdk/pull/2072 -> There is a
change in `pallet-referenda`. Now, the tracks are retrieved as a list of
`Track`s. Also, the names of the tracks might have some trailing null
values (`\0`). This means display representation of the tracks' names
must be sanitized.
* https://github.com/paritytech/polkadot-sdk/pull/5723 -> adds the
ability for these pallets to specify their source of the block number.
This is useful when these pallets are migrated from the relay chain to a
parachain and vice versa. (Not entirely sure it is breaking as it is
being marked as backward compatible).
* https://github.com/paritytech/polkadot-sdk/pull/6338 -> Update
Referenda to Support Block Number Provider
### Notable changes
* https://github.com/paritytech/polkadot-sdk/pull/5703 -> Not changes
required in the codebase but impact fastSync mode. Should improve
testing.
* https://github.com/paritytech/polkadot-sdk/pull/5842 -> Removes
`libp2p` types in authority-discovery, and replace them with network
backend agnostic types from `sc-network-types`. The `sc-network`
interface is therefore updated accordingly.
## What changes in Frontier
* https://github.com/polkadot-evm/frontier/pull/1693 -> Add support for
EIP 7702 which has been enable with Pectra. This EIP add a new field
`AuthorizationList` in Ethereum transaction.
Changes example :
```rust
#[test]
fn validate_transaction_fails_on_filtered_call() {
...
pallet_evm::Call::<Runtime>::call {
source: H160::default(),
target: H160::default(),
input: Vec::new(),
value: sp_core::U256::zero(),
gas_limit: 21000,
max_fee_per_gas: sp_core::U256::zero(),
max_priority_fee_per_gas: Some(sp_core::U256::zero()),
nonce: None,
access_list: Vec::new(),
authorization_list: Vec::new(),
}
.into(),
```
## ⚠️ Breaking Changes ⚠️
* Upgrade to Stirage hub v0.5.1
* Support for Ethereum latest upgrade (txs now have the
`authoriation_list` for support EIP 7702)

This PR adds the Snowbridge Inbound Queue V2 pallet to the runtime. It
also defines bridge primitives, including the message structure for
EigenLayer, and introduces the EigenLayerMessageProcessor to handle
messages coming from EigenLayer.
