[gRPC] Add new options to control the gRPC code generation. (#8298)

Browse Source 
The new options are:

-  `--grpc-filename-suffix` controls the suffix of the generated files;
-  `--grpc-use-system-headers` controls the type of C++ includes generated;
-  `--grpc-search-path` controls the directory that contains gRPC runtime;
-  `--grpc-additional-header` allows to provide additional dependencies for the generated code.
