This change makes the invocation of the deferred job clean-up
mechanism conditional. For submissions that require job tracking,
deferred clean-up is only required if any of the following
conditions are met:
1) Channel's deterministic flag is not set
2) Rail-gating is enabled
3) Channel WDT is enabled
4) Buffer refcounting is enabled
5) Dependency on Sync Framework
In case deferred clean-up is not needed, we clean-up
a single job tracking resource in the submit path. For
deterministic channels, we do not allow deferred clean-up to
occur and fail any submits that require it.
