Patch for //third_party/grpc git repository of OpenHarmony 3.1 codebase.

Building with -Werror with both clang and gcc requires some differences in which
warnings are disabled. Some warnings in clang is not known by gcc, so we are not
allowed to disable them, and the missing-prototypes warning ins only supported
for C++ by gcc.
