CMake: Support protobuf code gen; add pw_rpc
- Add proto.cmake and the pw_proto_library function. Like the GN
version, this generates code for .proto files.
- Provide CMakeLists.txt for pw_protobuf, pw_rpc, and pw_hdlc_lite.
- Add a Nanopb wrapper CMakeLists.txt with a cache variable for Nanopb,
similar to the variable for GN.
