This PR introduces the Snowbridge `system-v2` pallet and associated
runtime components
**Key Changes:**
* **Added `system-v2` Pallet:** Integrated the
`snowbridge-pallet-system-v2` pallet, providing functionalities for the
Ethereum side of the bridge.
* **Runtime API Integration:**
* Implemented the `ControlV2Api` trait in the runtime
(`operator/runtime/src/apis.rs`) to allow looking up the `AgentId`
associated with a `VersionedLocation`.
* **System V1 Compatibility:** Added the `system-v1` pallet
(`snowbridge-pallet-system`) and related configuration/code references
in various locations.
**Important:** This `system-v1` is included *solely* because the
`system-v2` pallet requires it for compilation and compatibility. It is
**not functionally used** in this runtime.

This PR adds Ethereum RPC API support to the node, enabling the
interaction with the node using standard Ethereum tools.
1. Integration of Frontier's Ethereum RPC modules (eth, net, web3,
txpool)
2. Added RPC configurations necessary for Ethereum compatibility
3. Implemented a BABE consensus data provider for handling pending
blocks
4. Added required dependencies and configurations in the node's service
5. Created necessary filter pools, block data caches, and notification
systems
6. Configured the RPC system to handle Ethereum API calls
7. Changed the transaction pool implementation to be compatible with the
fork-aware transaction pool
(https://github.com/paritytech/polkadot-sdk/pull/4639)
EDIT:
The new `transaction_pool` in `polkadot-stable2412` that comes with a
`fork-aware` feature, allowing different views of the transaction pool,
is not compatible with the current state in Frontier.
In Frontier the only supported pool is the `BasicPool`, that maintains a
similar behaviour to the one in `polkadot-stable2409`. I used this pool
directly.

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.
