Fix wheel event handling in WPEQtView
https://bugs.webkit.org/show_bug.cgi?id=313311
Reviewed by Adrian Perez de Castro.
On some platforms QWheelEvent will not have pixelDelta. Qt recommends
fallback to angleDelta when it is not available.
See https://doc.qt.io/qt-6/qwheelevent.html#pixelDelta-prop
Also, WPEEvent for scroll expects number of ticks if and only if
has_precise_deltas is false. This means that we should set
has_precise_deltas to true if we have pixelDelta.
Go to
https://developer.mozilla.org/en-US/docs/Web/API/Element/wheel_event
and check the wheel event is working.
