BlockId removal: runtime-api refactor (#13255)

* BlockId removal: refactor of runtime API

It changes the arguments of:
- `ApiExt` methods:  `has_api`, `has_api_with`, `api_version`
- `CallApiAt` method: `runtime_version_at`
from: `BlockId<Block>` to: `Block::Hash`

It also changes the first argument of all generated runtime API calls from: `BlockId<Block>` to: `Block::Hash`

This PR is part of BlockId::Number refactoring analysis (paritytech/substrate#11292)

* BlockId removal: refactor of runtime API - tests

- tests adjusted to new runtime API,
- some tests migrated from block number to block hash

* benchmarking-cli: BlockId(0) migrated to info().genesis_hash

`runtime_api.call()` now requires the block hash instead of BlockId::Number.
To access the genesis hash widely used in benchmarking engine the Client
was constrained to satisfy `sp_blockchain::HeaderBackend<Block>` trait
which provides `info().genesis_hash`.

* trivial: api.call(BlockId) -> api.call(Hash)

- Migrated all `runtime_api.calls` to use Hash
- Noteworthy (?):
-- `validate_transaction_blocking` in transaction pool,

* CallApiAtParams::at changed to Block::Hash

* missed doc updated

* Apply suggestions from code review

* ".git/.scripts/commands/fmt/fmt.sh"

* BlockId removal: Benchmark::consumed_weight

Little refactor around `Benchmark::consumed_weight`: `BlockId` removed.

* at_hash renamed

* wrong merge fixed

* beefy worker: merged with master

* beefy: tests: missing block problem fixed

* Apply review suggestion

* fix
