drm/xe: Add Indirect Ring State support
When Indirect Ring State is enabled, the Ring Buffer state and
Batch Buffer state are context save/restored to/from Indirect
Ring State instead of the LRC. The Indirect Ring State is a 4K
page mapped in global GTT at a 4K aligned address. This address
is programmed in the INDIRECT_RING_STATE register of the
corresponding context's LRC.
v2: Fix kernel-doc, add bspec reference
v3: Fix typo in commit text
Bspec: 67296, 67139
