If power state is retained between suspend/resume cycle, we don't need
to perform full GT re-initialization. Introduce runtime helpers for GT
which greatly reduce suspend/resume delay.
v2: Drop redundant xe_gt_sanitize() and xe_guc_ct_stop() (Daniele)
Use runtime naming for guc helpers (Daniele)
v3: Drop redundant logging, add kernel doc (Michal)
Use runtime naming for ct helpers (Michal)
v4: Fix tags (Rodrigo)
v5: Include host_l2_vram workaround (Daniele)
Reuse xe_guc_submit_enable/disable() helpers (Daniele)
