output: fix modifier stripping
DRM formats with an empty modifier list are invalid. Instead of
emptying the list, reduce it to { INVALID }.
Add a check to make sure the renderer and backend support implicit
modifiers, so that we don't fallback on e.g. Vulkan.
Closes: https://github.com/swaywm/sway/issues/6692
