xwayland: Check for implicit scanout availability
With implicit modifiers, DRM_FORMAT_MOD_INVALID is an allowed modifier,
to indicate that the server can support the format.
When looking for a scanout capable tranche with implicit modifiers, we
ought to check for the availability of a tranche with an invalid
modifier for the given format.
