* depreacte submit_finality_proof and introduce submit_finality_proof_ex instead

* propagate changes to the rest of runtime crates

* tests for new call

* suppress deprecation warning

* revert changes to benchmarks to avoid unnecessary compilation issues when integrating to other repos

## Pallet Operations
The main entrypoint of the pallet is the `submit_finality_proof` call. It has two arguments - the finalized
headers and associated GRANDPA justification. The call simply verifies the justification using current
validators set and checks if header is better than the previous best header. If both checks are passed, the
header (only its useful fields) is inserted into the runtime storage and may be used by other pallets to verify
storage proofs.
The main entrypoint of the pallet is the `submit_finality_proof_ex` call. It has three arguments - the finalized
headers, associated GRANDPA justification and ID of the authority set that has generated this justification. The
call simply verifies the justification using current validators set and checks if header is better than the
previous best header. If both checks are passed, the header (only its useful fields) is inserted into the runtime
storage and may be used by other pallets to verify storage proofs.
The submitter pays regular fee for submitting all headers, except for the mandatory header. Since it is
required for the pallet operations, submitting such header is free. So if you're ok with session-length
