lib/prompbmarshal: return back custom protobuf marshaler for lib/prompbmarshal.WriteRequest
...
The easyproto-based marshaler is 2x slower than the previous custom marshaler,
so let's stick with it. This improves the performance for sending data to remote storage at vmagent
and reduces CPU usage to pre-v1.97.0 levels.
