proto: add tests for unmarshalling invalid field numbers

This change adds tests for unmarshalling fields with various invalid field
numbers. Our current behavior is that proto.Unmarshal will return an error when
it sees zero and larger than max field numbers and return nil for reserved
ones, which matches the C++ behavior. (Note: depending on which parser helper
in the C++ implementation, one may need to call additional method to check the
result, which we don't have in Go)
