drm/i915: Stop inheriting IP_VER(12, 50)

All the platforms that inherit the media/graphics version
from XE_HPM_FEATURES / XE_HP_FEATURES just override it to another
version. Just set the version directly in the respective struct
and remove the versions from the _FEATURES macros. Since that was the
only use for XE_HPM_FEATURES, remove it completely.
