Make Wayland the Default for Wine on Wayland (Help checking stability)

[sHedC]

Description Now that Wine with true wayland support seems stable, and on Nvidia drivers more stable than XWayland, suggest that we move the default to use native Wine Wayland.

Proposal is to have Default wayland on wayland windows managers enabled unless DISABLE_WINE_WAYLAND flag is set, remove the WINE_EXPERIMENTAL_WAYLAND flag.

I have been using this under Wayland with Nvidia/ AMD and Proxmox VGPU my rides are usually between 40 min and 2 hours and its stable and seems more performant (no idea if that is the placebo effect)

Just a proposal at the moment
