- Added Functionality to pass ze_power_saving_hint_type_t to zeContextCreate included in the pNext extensions in ze_context_desc_t. - Enables handling a hint value 0-100 with 0 being no power savings and 100 being maximum power savings. - ZE_RESULT_ERROR_INVALID_ENUMERATION is returned given an invalid hint. Related-To: LOCI-2567 Signed-off-by: Spruit, Neil R <neil.r.spruit@intel.com>
