roll: pigweed Revert "pw_protobuf: Force use of callbacks for oneof"

This reverts commit 53d4032b027055342c7321bef95e8a23e805c74c.

Reason for revert: Downstream dependency issues.

Original change's description:
> 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.
