xwayland: Add proper support for telling if a format/mod is supported

This adds to xwl_glamor_is_modifier_supported, where if feedback
is in use we will check that the format/mod is allowed in any
device advertised by the compositor.

Reviewed-by: Michel Dänzer <mdaenzer@redhat.com>

[ Michel Dänzer:
* Move dev_formats declaration to where it's used in
  xwl_feedback_is_modifier_supported
* Add curly braces around multi-line statement in
  xwl_glamor_is_modifier_supported ]
