Francois Dugast 770bd1d341 drm/xe/hw_engine_group: Ensure safe transition between execution modes 
Provide a way to safely transition execution modes of the hw engine group
ahead of the actual execution. When necessary, either wait for running
jobs to complete or preempt them, thus ensuring mutual exclusion between
execution modes.

Unlike a mutex, the rw_semaphore used in this context allows multiple
submissions in the same mode.

v2: Use lockdep_assert_held_write, add annotations (Matt Brost)

v3: Fix kernel doc, remove redundant code (Matt Brost)

v4: Now that xe_hw_engine_group_suspend_faulting_lr_jobs can fail,
    propagate the error to the caller (Matt Brost)
