[PATCH i-g-t 1/2] lib/xe/xe_query: Add xe_gt_type() and xe_is_main_gt() helpers

[Marcin Bernatowicz]

Introduce xe_gt_type() to return the GT type from query data. This
replaces open-coded access in xe_is_media_gt() and makes it easy to
add new GT-specific helpers. Add xe_is_main_gt() for MAIN GT checks.
