Fix GPU cache size unit from KiB to B

I'm checking with the owner of the Thunk specification what unit we should be reporting.

Thanks.

Currently, ROCR's hsa_cache_get_info(HSA_CACHE_INFO_SIZE) returns size in byte unit in cpu agent but returns size in KiB unit in gpu agent.

Maybe, ROCT interface returns size in KiB unit. And to fix above problem, fix ROCT/ROCR, to ROCT returns cpu cache size in KiB unit and ROCR returns cpu/gpu cache size in byte unit.

@fxkamd Did we ever get a response on this?

This was resolved in ROCr in ROCm 4.3 (502dc3a9c99dc Get GPU cache information from KFD) EDIT: We can't change this without breaking backwards-compatibility. And ROCr successfully handles it now so it's being closed for that reason.
