Starting with Level Zero driver version 1.17, zeCommandListAppendHostFunction is part of the core API, so it can be called directly instead of being resolved via zeDriverGetExtensionFunctionAddress. For older drivers, keep resolving it dynamically as an extension. Update the ZeHostTaskExtension::zeCommandListAppendHostFunction function pointer type to match the real API signature (ze_host_function_callback_t, const void *pNext, ze_event_handle_t *phWaitEvents), and fix the call site in command_list_manager.cpp to cast pfnHostTask to ze_host_function_callback_t instead of void *, avoiding an invalid void* to function-pointer conversion.
