f84a5fbee9 feature: add host functions workers 
* add common host function worker interface
* add worker as a single thread per csr with 3 modes
* add logic for waiting on internal tag, check gpu hang
* if tag is in pending state, read callback data, run callback
and signal completion
* threads will exit the work loop once stop request
is called in finish
* add multi thread unit tests

40ce5eb55e fix: Fix DirectSubmissionController deadlock with try_lock pattern 
Related-To: NEO-13325

Replace blocking obtainUniqueOwnership() with tryObtainUniqueOwnership()
in critical paths to prevent deadlock between controller thread holding
directSubmissionsMutex and submission threads holding CSR locks.

Changes:
- Add CommandStreamReceiver::tryObtainUniqueOwnership() method
- Use try_lock in checkNewSubmissions() and context group idle detection
- Skip contended CSRs instead of blocking (conservative approach)
- Add comprehensive unit tests for try_lock functionality

Fixes deadlock scenario where registerDirectSubmission() waits for
directSubmissionsMutex while checkNewSubmissions() holds it and waits
for CSR ownership locks.

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).

Without this, temporary allocation might not be cleaned before next copy
operation.
If a second copy operation is passed same ptr that has been reallocated,
there will be a pagefault.
