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.

drm/xe/pf: Expose PF service details via debugfs
...
For debug purposes we might want to verify which registers values
PF is sharing with VFs and to view which VF/PF ABI versions were
negotiated by the VFs. Plug the 'print' functions already provided
by the PF service code into our debugfs.

drm/xe/pf: Expose SR-IOV VFs configuration over debugfs
...
We already have functions to configure VF resources and to print
actual provisioning details. Expose this functionality in debugfs
to allow experiment with different settings or inspect details in
case of unexpected issues with the provisioning.
As debugfs attributes are per-VF, we use parent d_inode->i_private
to store VFID, similarly how we did for per-GT attributes.
