Handle destroyed subsurfaces

Browse source 
Damage subsurfaces when they are destroyed. Since subsurfaces don't have an
unmap event we need to do that on destroy.

We also don't want to keep a sway_view_child when the wlr_subsurface has been
destroyed.

Fixes https://github.com/swaywm/sway/issues/3197
