gma: Add cursor infrastructure

Allow ARGB cursors of 64x64, 128x128 or 256x256 pixels. Valid positions
depend a lot on the hardware generation, so we'll accept arbitrary
integer values in the interface and filter them internally. An out of
bounds cursor will simply be invisible.

It's unclear if the parameters also apply to other GFX hardware. Thus,
we keep the types in the GMA sub-package for now.
