wayland: set an opaque region

Browse Source 
Apparently a part of the wayland spec. A compositor may use a surface
that has set part of itself as opaque for various optimizations. For
mpv, we simply set the entire surface as opaque as long as the user has
not set alpha=yes (note: alpha is technically broken in the wayland EGL
backend at the time of this commit but oh well). wlshm is always opaque.
Fixes #8125.
