* 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 Related-To: NEO-14577 Signed-off-by: Kamil Kopryk <kamil.kopryk@intel.com>
