All LearningModelSessions created from a common LearningModelDevice should share the same thread pool (#11457)
* Share thread pools between devices

* make tests reuse device

* Change cpu thread pool options for dml sessions to use 1 thread with no spinning

* fix test failure

* Update missing type constraints for dft

* Add comment and rename inference session parameter

* default missing causing inconsistent test behavior
