Re-add the internal file //absl/string/internal/has_absl_stringify.h to unblock

releasing Abseil and GoogleTest.

GoogleTest referenced this internal file and this internal trait.  Since
simultaneous releases are not possible since once release must reference
another, we will temporarily add this back.
