upgpkg: discord 0.0.54-2: refactor, fix autostart, add deps, use wayland

* Slightly refactor PKGBUILD
* Fix autostart desktop file
* Add optional dependency used in official arch package
* Include patch to allow Krisp noise suppression support
* Add install file to inform user about this change
* Use Wayland instead of Xwayland in a Wayland session by setting
  Electron flag `ozone-platform-hint` to auto (default is X11)
