drm/xe/guc: Add PF2GUC_UPDATE_VF_CFG to ABI

In upcoming patches the PF driver will add support to change VFs
configuration and will need to use PF2GUC_UPDATE_VF_CFG messages.
Add necessary definitions to our GuC firmware ABI header.

Definitions of the GuC VF Configuration KLVs used by this action
are already present in abi/guc_klvs_abi.h
