Subject: [PATCH 18/24] UI: Disable and ignore Always On Top on Wayland
 platforms

This is a dangerous operation on Wayland, and is crashing not only
OBS Studio but also the whole compositor. Let's disable it for now
when running as a native Wayland client.

Some compositors (GNOME Shell, Plasma) still allow setting this
option on the window menu.
