Add QTestPrivate::ensurePositionTopLeft() for reliable positioning

Browse Source 
Implement ensurePositionTopLeft() to set a window's position
to the available top-left corner and verify that it is correctly
positioned.

Incorrect updates to window.position and window.framePosition have
been identified as one of the main sources of flakiness on
Opensuse. This test function addresses this issue and improves test
reliablity.
