Change on-the-wire protocol names to include genesis hash & fork id (#11938)

Browse Source 
* Rename transactions protocol to include genesis hash

* Add protocol name generation to sc_network::utils

* Use utils functions for transactions protocol name generation

* Extract protocol name generation into public module

* Use sc_network::protocol_name::standard_protocol_name() for BEEFY and GRANDPA

* minor: add missing newline at EOF

* Change block-announces protocol name to include genesis_hash & fork_id

* Change protocol names to include genesis hash and fork id

Protocols changed:
    - sync
    - state
    - light
    - sync/warp

* Revert "Use sc_network::protocol_name::standard_protocol_name() for BEEFY and GRANDPA"

This reverts commit cd60a95a3face397e1b67f4bc95dd0f2b581bfae.

* Get rid of `protocol_name` module
