Moved tests into gui/kernel/ and gui/qopengl/
This commit moves tests from test/auto/ into more appropriate locations (i.e. matching the locations in the Qt source): - qscreen and qwindow are moved into gui/kernel/ - qopengl is moved into gui/qopengl/ Note: qscreen is disabled for now since it is broken on Linux (see QTBUG-22554).
