drm/xe/pf: Allow configuration of VF thresholds over debugfs

Initial values of all thresholds used by the GuC to monitor VF's
activity is zero (disabled) and we need to explicitly configure
them per each VF. Expose additional attributes over debugfs.

Definitions of all attributes are generated so we will not need
to make any changes if new thresholds would be added to the set.
