Revert "Windows QPA: Call QWSI::flushWindowSystemEvents() from WM_PAINT for full update only"
This reverts commit a81dfb32d6f9e7a407567511c20b59e537f6a063.
Paint immediately on WM_PAINT in all cases in order to
avoid flicker on resize.
The cases mentioned in commit a81dfb should no longer
apply:
- QTBUG-38327: QGLWidget is not supported in Qt 6.
- QTBUG-39842: Fixed by using ExcludeUserInputEvents.
Fixes: QTBUG-89688
