[PATCH i-g-t 17/25] lib/kms: Add helpers to query igt_format_mods

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add three new helpers for igt_format_mods:
- igt_format_mods_has_format_and_modifier()
- igt_format_mods_has_format()
- igt_format_mods_has_modifier()

These should be useful to some tests, avoiding for the tests
to iterate the igt_format_mods directly.
