[native] use grpc_clients client in native_rust_library

Summary: replaced the old grpc clients with the new one with an interceptor from shared/grpc_clients. i also updated build.rs to get the codeVersion from CommCoreModule.h. lastly, i removed unused dependencies and dead code.

Test Plan:

• unit tested the code version change
• sent a request to local identity service from native_rust_library and verified the request was received and contained the code version metadata
• built the native app for iOS simulator successfully
