- Support in the L0 Loader for https://oneapi-src.github.io/level-zero-spec/level-zero/latest/core/EXT_Driver_DDIHandles.html#ze-extension-driver-ddi-handles
- To improve the speed for each call of L0 apis into the correct driver, the new support enables for the driver to allocate a header that stores that driver's ddi tables such that the Loader does not need to perform translation of handles to/from ze_object_t.
- Given a driver supports the new extension, the loader will no longer create the ze_object_t and instead use the packed ddi tables in each handle_t.
- The code has been refactored such that the legacy path will continue to work for the driver that has not converted over without interfering with a driver which now uses the "fast" path.
- This new code path also removes the need for handle translation by the user if the drivers all support the new extension.
