drm/xe/pf: Add thresholds to the VF KLV config

We are pushing threshold KLV to the GuC immediately during the
threshold provisioning, but those configs will be lost during a
GT reset.  Include threshold KLVs while encoding full VF config
buffer to make sure the GuC receives all of the config KLVs.
