Fix touch being ignored when down and up are in the same frame
The Wayland protocol gives no guarantees about which events are part of
a frame, so handle the case where we receive wl_touch.down and
wl_touch.up within the same frame.
Fixes: QTBUG-89680
Change-Id: Ie0b9d2fb950fb0d9a6af8dd8ad2fa55a5efa71e6
Pick-to: 5.15 6.1 6.0
