[roll pigweed] pw_software_update: Add pw_protobuf-based service

Previously, pw_software_update only had a nanopb RPC
BundledUpdateService. This commit adds a new version of the service that
uses pw_protobuf RPC.

The service was essentially copy-pasted from the nanopb version, with
changes made to the RPC method handlers to use all of the new types.
