wayland: Keep touch sequence when touched surface is destroyed
requested to merge work/zzag/dont-cancel-touch-sequence-when-touched-surface-is-destroyed into master
If a touched surface is destroyed, we don't want to cancel the entire touch sequence. Furthermore, during dnd, it's not illegal to destroy the origin surface after starting the drag operation, the only relevant part is the source data device.
