Wait for explicit sync support

[LukeShortCloud]

Explicit sync support in XWayland and KDE Plasma will provide better support for NVIDIA proprietary graphics drivers on Wayland (including better Gamescope support). We need to wait for the following releases to come to Arch Linux before making a new release of winesapOS.

Proprietary and open kernel NVIDIA driver:

• Linux 6.8
  • https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27226
• Gamescope 3.14.3
• KDE Plasma 6.1.0
  • A backport to 6.0 was proposed but closed (not merged).
  • Expected in 2 weeks
• XWayland 24.1.0
  • Expected in 2 months
• NVIDIA 555 (optional for explicit sync Vulkan WSI support)
  • https://www.phoronix.com/forums/forum/phoronix/latest-phoronix-articles/1457174-xwayland-24-1-planned-for-release-next-month-with-explicit-sync-other-features
  • KDE Plasma 6 does not use this feature. It is expected for KDE Plasma 7.

  • Expected in 3-5 months from now

NVK Mesa driver:

• Linux 6.10
  • https://lore.kernel.org/dri-devel/20240430155453.21132-1-mohamedahmedegypt2001@gmail.com/T/#u
• Mesa 24.1.0
  • NVK explicit sync support
    • https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/24795
  • Optional for explicit sync Vulkan WSI support for NVK on Xorg
  • Expected in 2 months

Once all of these features have been merged and are available in Arch Linux, we could look into removing Xorg completely and rely on Xwayland instead.

KDE Plasma 6 still has a hard dependency on Xorg (even with Xwayland) so removing Xorg will not be in scope anytime soon.
