Implemented QWidget's move() vs setGeometry() distinction in QWindow.

Implemented QWidget's move() vs setGeometry() distinction in QWindow.

QWidget's move() sets the position of the window including the window
frame, unlike setGeometry(). There was no equivalent for this in
QWindow, so several QWidget auto-tests were failing. Now we add
setFramePos() to achieve the same purpose in QWindow.

This fixes tst_QWidget::windowState(), which uses move().
