roll: pigweed pw_protobuf: Force use of callbacks for oneof

pw_protobuf's message structures previously generated each of the
members of a oneof group as a separate struct member, allowing multiple
of them to be set to serialize semantically-invalid wire messages.

This replaces oneof struct member generation with a single callback for
the entire oneof group, allowing the user to encode/decode the desired
oneof field using the wire stream encoder and decoder.

The old oneof behavior is kept behind a protoc plugin flag to aid
downsteam migration. This flag is currently only activated in Bazel
builds.
