[PATCH v2 i-g-t 0/2] Fix xe_eudebug_online@interrupt-other test

["Dominik Karol Piątkowski" <dominik.karol.piatkowski@intel.com>]

xe_eudebug_online@interrupt-other test fails due to preemption
interfering with it.

In order to fix it, set the preempt_timeout_us for engine_class used in
this test to maximum for the duration of the test.

This series introduces the following engine_class helpers:
 - xe_sysfs_engine_class_get_property
   Convenience wrapper to get value of given property for given engine
   class on given gt.
 - xe_sysfs_engine_class_set_property
   Convenience wrapper to set given property for given engine class on
   given gt to given value.

v2:
   -Move helpers from lib/xe_eudebug to lib/igt_sysfs
   -Improve readability in xe_eudebug_online adjust commit
   -Add justification in message of xe_eudebug_online adjust commit
