Zello-sysman tool does not support testing all L0 OneAPI spec metric types

[eero-t]

https://github.com/intel/compute-runtime/blob/master/level_zero/tools/test/black_box_tests/zello_sysman.cpp#L1150

Is lacking options for testing metrics support for:

• PSUs: https://spec.oneapi.io/level-zero/latest/sysman/api.html#psu
• Fans: https://spec.oneapi.io/level-zero/latest/sysman/api.html#fan

Which have been supported by the public level-zero headers + loader already for months.

thanks @eero-t . very likely we haven't added those because we dont have support in the driver yet, see here https://github.com/intel/compute-runtime/blob/d129cca4b0d073e5f0234a18d7cc8a36dea1cfb7/level_zero/api/sysman/zes_sysman_api_entrypoints.h#L451

Once we have support (no ETA at this moment), we could add something to zello_sysman.

@jandres742 I would think how backend handles unimplemented frontend APIs to also be obviously of interest. E.g. to verify that those are also done according to spec / provide correct return value (see: https://github.com/intel/compute-runtime/issues/510).

While more extensive support for APIs could wait until they are properly supported by backend, I think test tool could have basic support for all APIs that just calls enumeration functions and lists how many items are available (if any).

PSU and Fan tests are still missing (no options listed for them by zello_sysman).
