Wine 9.0, add '--with-wayland' to build arguments

Description:

As of Wine 9.0, a WIP wayland driver is available that can be optionally enabled via a registry key. This is advertised on the new Wine changelog as being experimental, but doesn't actually affect usage unless users enable it via registry key. Currently, users are completely unable to use the registry key because of the missing flag.

Individuals in the community have compiled wine themselves and tested the Wayland driver to great success, but there is currently some confusion about why those wine registry keys aren't working for those running arch-based systems when they grab the latest binary release from pacman. While this is an issue about a feature that is technically optional, native wayland rendering has been anticipated for some time and is advertised front-and-center as being something you should be able to do on the wine 9 release announcement.

Additional info:

• package version(s): wine 9.0-1

Steps to reproduce:

1. sudo pacman -S wine
2. Run wine reg.exe add HKCU\\Software\\Wine\\Drivers /v Graphics /d x11,wayland as is advertised on the wine 9 announcement
3. Run DISPLAY= winecfg (or any graphical windows app) to unset the X display as instructed, wine will error out in the terminal complaining that no X11 window is set and that there is no driver available.
