b982cba5ce drm/xe/pf: Show VFs LMEM provisioning summary over debugfs 
While we can already view individual VF LMEM provisioning using
lmem_quota debugfs attribute, we want to have unified way to show
summary across all VFs, like we do for GGTT or GuC doorbells/IDs.

For feature enabling and testing purposes, allow to restore saved

c4f5ded082 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.

e42a51fb9c 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.
