drm/xe/guc_submit: Introduce pause/unpause() helpers for PF

Browse source

Introduce pause/unpause() helpers which stop/start further runs of
submission tasks on given GuC and can be called from PF context. This
is in preparation of usecases where we simply need to stop/start the
scheduler without losing GuC state and don't require dealing with VF
migration.
