For execlists backend, current implementation of Wa_22011802037 is to
stop the CS before doing a reset of the engine. This WA was further
extended to wait for any pending MI FORCE WAKEUPs before issuing a
reset. Add the extended steps in the execlist path of reset.
In addition, extend the WA to gen11.
v2: (Tvrtko)
- Clarify comments, commit message, fix typos
- Use IS_GRAPHICS_VER for gen 11/12 checks
v3: (Daneile)
- Drop changes to intel_ring_submission since WA does not apply to it
- Log an error if MSG IDLE is not defined for an engine
