* Define SimpleRuntimeVersion

* Set R/WococoBridgeHub bundle runtime version

* Use indirect runtime calls for RialtoParachain

* Code review fixes

* Small changes

* Define generic bridge pallets call structs

* polkadot-core SignedExtension simplifications

- we don't seem to need to pass the Call as a generic param
- we can use codec(skip) instead of implementing Encode and Decode

* Split BridgeHubRococo and BridgeHubWococo calls

* code review fixes

Wait until the initialization transaction is finalized/lost.

* TypedLaneId -> LaneId

* fix benchmarks compilation

* expose metrics of on-demand relay chain headers sync from with-parachain complex relays

* spelling

* remove renundant arg

* Simplify submit_and_watch_signed_extrinsic

The way submit_and_watch_signed_extrinsic is used now, we can always
derive the SignParam from other params. If in the future we need more
customization possibilities, we can define a new method.

* Simplify submit_signed_extrinsic

* Send maybe_batch_tx as a parameter

Send `maybe_batch_tx` as a parameter to `submit_proof()`. This way we
can deduplicate the logic that submits the extrinsic for
`messages_source and `messages_target` and we can simplify the logic in
the race loop a bit.

* Define BatchProofTransaction

Deduplicate BatchConfirmationTransaction and BatchDeliveryTransaction by
replacing both of them with BatchProofTransaction

* Define ChainWithUtilityPallet and BatchCallBuilderConstructor

- Define `ChainWithUtilityPallet` in order to be able to associate the
  batching functionality with chains
- Defining `BatchCallBuilderConstructor` in order to have a more reliable
  way of checking whether an end of a messages pipeline supports batching
  or no. `BatchCallBuilderConstructor::new_builder()` returns an
  `Option<BatchCallBuilder>`.This is a bit safer because each time a caller
  tries to start creating a batch call, it will call `new_builder()` and
  will be required to handle the returned `Option`. Before we only had a
  bool `BATCH_CALL_SUPPORTED` the caller could have forgetten to check.

* impl prove_header in OnDemandHeadersRelay

* impl OnDemandParachainsRelay::prove_header (needs extensive tests)

* added a couple of TODOs

* return Result<Option<BatchTx>> when asking for more headers

* prove headers when reauire_* is called && return proper headers from required_header_id

* split parachains::prove_header and test select_headers_to_prove

* more traces and leave TODOs
