  [clang] treat [[gnu::flag_enum]] as equivalent to [[clang::flag_enum]] (#219105)

GCC gained a `[[gnu::flag_enum]]` attribute for consistency with clang
in GCC 15. With this patch, the `[[gnu::flag_enum]]` is recognized and
handled equivalently to `[[clang::flag_enum]]`.

The patch introducing `[[gnu::flag_enum]]` in GCC is
https://github.com/gcc-mirror/gcc/commit/1914ca8791ce4e0ba821e818cb6f86c76afdb6f2.
GCC treats `[[clang::flag_enum]]` as equivalent to `[[gnu::flag_enum]`.
