This PR extends the chainHead_follow to produce the results of the other chainHead methods

  • chainHead_storage, chainHead_call, chainHead_body are now plain methods
  • mpsc::channel is added between the chainHead_follow and the rest of the methods
  • unique operation ID to identify the response in the chainHead_follow events is generated by the subscription management
  • BlockGuard struct is extended with the following fields:
    • the unique operation ID
    • the Sender part of the channel to communicate the response back to the chainHead_follow
  • chainHead_follow merges the Recv part of the channel to forward responses of methods back to the user
  • remove the events produced by the prior subscriptions that are now plain methods
  • testing is adjusted and added unique ID validation

Closes: #14638
