proto: expose package-private equalField.
There is a demand for comparing protobuf.Value-s.
One use case is when one wants to compare just one field via reflection.
Another is when one wants to iterate over fields and check for diffs.
Existing diff packages are recommended only for tests as they panic on error.
Exposing equalField will prevent excessive branching of proto/equal.go code.
