WindowServer+Userland: Pass wallpapers as Gfx::Bitmap instead of path

Browse source 
The WindowServer _really_ does not need to know the filesystem path to
it's wallpaper, and allows setting arbitrary wallpapers (those outside
of `/res/wallpapers`).

The GUI::Desktop will keep track of the path to the wallpaper (if any),
and save it to config if desired (to be persisted).

This avoids the need to `unveil` paths to the wallpaper, fixing #11158
