drm/xe/multi_queue: Add GuC interface for multi queue support

Browse source

Implement GuC commands and response along with the Context
Group Page (CGP) interface for multi queue support.

Ensure that only primary queue (q0) of a multi queue group
communicate with GuC. The secondary queues of the group only
need to maintain LRCA and interface with drm scheduler.

Use primary queue's submit_wq for all secondary queues of a multi
queue group. This serialization avoids any locking around CGP
synchronization with GuC.

v2: Fix G2H_LEN_DW_MULTI_QUEUE_CONTEXT value, add more comments
    (Matt Brost)
v3: Minor code refactro, use xe_gt_assert
v4: Use xe_guc_ct_wake_waiters(), remove vf recovery support
