Make setting QT_SCALE_FACTOR work on Wayland

Browse Source 
QWindow geometry accessors return geometry in device
independent pixels. Normally this coordinate system
is equivalent to the Wayland native coordinate system,
but this is not the case when QT_SCALE_FACTOR is set.

Replace QWindow geometry calls with the helpers from
QPlatformWindow which return geometry in the native
coordinate system:

QWindow::geometry() -> QPlatformWindow::windowGeometry()
QWindow::frameGeometry() -> QPlatformWindow::windowFrameGeometry()

Task-number: QTBUG-87762
