e80b84e699 feature: Don't terminate ULLS contexts if busy context exists 
Enhanced direct submission idle detection to ensure that
ULLS contexts are not terminated if any context in the same group
is still busy or has pending work.
Idle detection now accurately considers the state of all CSRs
in a context group before terminating any direct submission.
Controlled with DirectSubmissionControllerContextGroupIdleDetection
(note: the feature is disabled by default in first step).

d4c1631ac7 performance: don't wait for paging fence on user thread 
Related-To: NEO-12197

Currently for new resources user thread must wait before submitting
actual workload. With this commit, instead of waiting on user thread,
request is sent to background ULLS controller thread and additional
semaphore is programmed. ULLS controller will perform actual wait
and signal semaphore when paging fence reaches required value.

b109094e4b fix: move ulls controller stop thread 
Move ulls controller thread stopping to execution environment
destructor. This removes the vptr race from ulls controller destructor.

Put tests that are actually running the ulls controller into multi thread
tests.

That way they are compiled with thread sanitizer and removes the
variable test time from traditional ULTS.

411ed1c643 feat: direct submission variable timeout 
Add mechanism to increase direct submission timeout up to a maximum
value when no new submissions were made since last sleep.

This should help in workloads that have delays between iterations larger
than current direct submission controller timeout.
