emulators/wine8: Remove expired port

2024-10-30 emulators/wine8: The transition to Wine 9.0 should be mostly done now

emulators/wine8: Deprecate in favor of the main wine port

This port served to support a transition period from Wine 8.0 to
Wine 9.0 which, after half a year, should be mostly complete.

As reminded by a build failure with GCC 14, this codebase is not
maintained by upstream any longer, so initiate deprecation (with
an initial EXPIRATION_DATE of 2024-10-30).

On the way, release maintainership.

emulators/wine8: New port, cloning emulators/wine

Wine 9 has been released some weeks ago and it's time to upgrade the
main emulators/wine port. However, there may be some regressions (in
particular around WoW64), so create emulators/wine8 as a clone of the
state before the version upgrade as a fallback. [1]

Since it is rarely, if ever, used, in particular in this context,
remove the MONO option.
