As per DDI handles extension, global ddi table pointers will be included in every L0 handle. This change is focused on initialization of the global objects and reuse of them within zeGet...ProcAddrTable functions to avoid duplication of per component ddi table definitions Related-To: NEO-13121, NEO-13917 Signed-off-by: Mateusz Jablonski <mateusz.jablonski@intel.com>
