drm/xe/guc: Enable the Dynamic Inhibit Context Switch optimization
The Dynamic Inhibit Context Switch is an optimization aimed at reducing
the amount of time the HW is stuck waiting on an unsatisfied semaphore.
When this optimization is enabled, the GuC will dynamically modify the
CTX_CTRL_INHIBIT_SYN_CTX_SWITCH in the CTX_CONTEXT_CONTROL register of
LRCs to enable immediate switching out on an unsatisfied semaphore wait
when multiple contexts are competing for time on the same engine.
This feature is available on recent HW from GuC 70.40.1 onwards and it
is enabled via a per-VF feature opt-in.
v2: rebase
v3: switch to using guc_buf_cache instead of dedicated alloc
v4: add helper to check for feature availability (Michal), don't enable
if multi-lrc is possible.
