[win32k]

- Add mask offset coordinates to GreStretchBltMask parameters, add code to handle a mask offset
- Only fail if the mask is smaller than the color bitmap, print sizes in this case
- Adapt callers to GreStretchBltMask changes
- DrawIcon: use new features to combine mask and color images
- Mouse control panel now shows cursors again (masks still need some work), fixes ~15 user32:cursoricon tests
