winewayland: Treat fully transparent cursors as hidden.
SDL 2.0.18 and newer (including SDL 3) set a fully transparent cursor
object when hiding the cursor (instead of using a NULL cursor handle).
Detect this case and treat it as a request to hide the cursor, to make
our locking/relative-motion heuristics work.
