backend/drm: track cursor FB in wlr_drm_connector_state

Browse source 
Use the same logic for cursor FBs as we currently use for primary
FBs. This also fixes the same bug as [1] but in a different, more
robust way.

The new logic integrates better with atomic and will be required
anyways in the future when set_cursor will be superseded by a better
API.
