Subject: Fix touch input for html's popup in quick impl

Ammends 292f573f4e. Now that touch events are forwarded to popup
delegate also instead of synthesized mouse events, the bug with touch
event being ignored became present. Also extend testing of touch
events for html popups.

Task-number: QTBUG-79254
Fixes: QTBUG-103217
Pick-to: 6.2 6.3
Change-Id: I097a6617493355c7603fef8eb41025e299a6e809
