Thad House 8b8b634f65 [wpiutil] Change C++ protobuf to nanopb (#7309)
The Google C++ protobuf implementation has issues with dynamic linkage across DLL boundaries because it uses global variables.  It also has a compile-time dependency because the protoc version must exactly match the libprotobuf version.  Using nanopb with a customized generator fixes both of these issues.
