[roll third_party/pigweed] pw_protobuf_compiler: Support strip_import_prefix
Use ProtoInfo.proto_source_root to determine output and include paths.
Because use of strip_import_prefix makes rules_proto place files into a
directory in the output directory, and protoc will prepend the output
directory path when outputting the generated files, we want to special
case the output directory if the proto is already there.
In addition, we return a CcInfo with include path also containing the
proto_source_root so users can find the headers in the output dir.
Switch pw_rpc to using new rules since they use the strip_import_prefix
feature, so the changes are tested.
Support for nanopb is added so pw_rpc/nanopb tests can compile.
