Update gRPC, its gn template, plugin registry and absl_component_deps

1. A deduplication logic is added to BUILD.chromium.gn.template because
   a source file appears multiple times in input and GN cannot handle
   that.
2. gRPC now uses `absl::Random`
3. `plugin_registry/grpc_plugin_registry.cc` is updated (this is
required) because resource quota handling changed.
