Proposal for a new plane SIZE_HINTS property to essentially
replace the cursor size caps, based on recent discussion
in this gitlab bug:
https://gitlab.freedesktop.org/drm/intel/-/issues/7687

As for userspace, so far I only did a quick modetest
blob decoder (mainly to verify that it looks correct):
https://gitlab.freedesktop.org/vsyrjala/libdrm/-/commits/plane_size_hints

Didn't yet update my modesetting ddx cursor size patch
to use this or anything.
