[clang-tidy] performance-inefficient-vector-operation: Support proto repeated field

Summary:
Finds calls that add element to protobuf repeated field in a loop
without calling Reserve() before the loop. Calling Reserve() first can avoid
unnecessary memory reallocations.

A new option EnableProto is added to guard this feature.
