drm/xe/tests: Add pre-GMDID IP descriptors to param generators

Recently introduced kunit parameter generators were based on
the existing arrays which have only GDMID-based IPs and didn't
take into account IP definitions from pre-GMDID era.

Add test only arrays with pre-GMDID IPs (as those will not change)
and extend param generators to start iterating over them.
