aarch64: Update FLAGS field documentation comment in aarch64-cores.def
With the cleanup of the arch features in GCC 13 the comment on the FLAGS field in aarch64-cores.def
is now outdated. It's now a comma-separated list rather than a bitwise or.

gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (FLAGS): Update comment.
