[PATCH i-g-t 2/2] tests/intel/xe_pm: Add a check for power management capability

[Jakub Kolakowski]

Add a check for power management capability of device tested in tests
related to D-states. Currently if test is started on configuration
that does not support the PM capability it doesn't skip, instead
depending on test it may fail, abort or timeout.
With this change test will skip with a clear message why it did.
