[autotests] New test case to verify cursor changes correctly in effects

Browse source 
The test case verifies that setting an override cursor during mouse
interception works and that it's also possible to change it. When
ending mouse interception the cursor image should be adjusted again.

The test shows that when mouse interception starts KWin should send
a pointer leave event to the current focused window and similar needs
to handle the stop of mouse interception.
