screen-cast: Fix segfault when drawing cursor
Add a sanity check if the cursor is on screen and cursor texture data
is available. This prevents a potential segfault when trying to access
non-existing texture data.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1446
(cherry picked from commit efb577efb0cd23e98caad1544f556cb82130f8e0)
