drm/xe/pf: Add functions to save and restore VF GuC state

Browse source

To successfully migrate a VM with attached GPU VF we also need to
migrate VF's GuC state. Add necessary functions that interacts with
GuC to save and restore a VF GuC state. We will start using them in
upcoming patches.

Since VF migration requires many more changes in the driver, enable
those functions only under debug config.
