lib/i915: Add intel_display_ver() and use it in display tests/libs
Display code should check the display version of the platform rather
than the graphics version; on some platforms these versions won't be the
same.
v2:
- Continue to use intel_gen() in draw_rect_blt() since it's checking
the version of the blitter engine (graphics) rather than the display
version. (Jose)
- Rename some gen -> display_ver in kms_universal_plane too. (Jose)
