pw_protobuf: better use of blob count in encoder

Repeated nested messages would each get their own blob, which did not
scale very well for some messages.

This is a small fix to help some users while waiting for an improved
pw_protobuf encoder.

Note: the second template argument for the NestedEncoder is now moot,
        and should always be set to the same as the first. In order not
        to break any code relying on this, it has been left alone.

Testing done:
- tested on a proto that would previously cause a RESOURCE_EXHAUSTED
  error, now properly encodes
