Flickable: Don't accept ScrollEnd wheel eventHEADdev

...to fix snapping behavior of
ListView { snapMode: SnapOneItem; delegate: ListView { ...} }

It doesn't accept the event with ScrollBegin phase, so shouldn't do it
for the ScrollEnd phase either.

Accepting ScrollEnd unconditionally broke nested ListView, for example,
where the higher-level one wouldn't snap back to the delgate and would
get stuck in a moving state -- that is, until you click it so that the
mouseReleaseEvent cleans it up.

Fixes: QTBUG-126042
Pick-to: 6.5 6.7 6.8
