pw_rpc: Simplify ServerReader/Writer Open API

- Update the Reader/Writer Open function to take a single, simpler
  template argument.

  Before:

    RawServerWriter::Open<&ServiceNameImpl::MethodName,
                          CalculateMethodId("MethodName")>(...)
  After:

    RawServerWriter::Open<pw_rpc::raw::ServiceName::MethodName>(...)

  This uses the new MethodInfo type to extract information about the
  RPC method, avoiding the need for the user to calculate the method ID.
- Remove the CalculateMethodId() function, which is no longer necessary.
  This keeps method IDs as an implementation detail that is hidden from
  pw_rpc users.
- Add tests for opening responder objects for unary RPCs.
