[PATCH v3 04/11] drm/xe/multi_queue: Refactor check for multi queue support for engine class

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

xe exec queue code is using a check to see if a class of engines support
multi queue. This check is also needed by other code, so move it to
xe_gt and export it for others.
