drm/xe/guc: Add more KLV helper macros

Browse Source 
In upcoming patches we will want to generate some of the KLV keys
from other macros. Add MAKE_GUC_KLV_{KEY|LEN} macros for that and
make sure they will correctly expand provided TAG parameter. Also
fix PREP_GUC_KLV_TAG to also work correctly within other macros.
