feature(debugger): Force GRF count to 128

System Routine changes for implementing large-grf debugging
will result in GRF count of 256 being reported for kernels
in all GRF modes. Applications using L0 Debug API do not
yet have a way to determine actual GRF count for kernel.

This commit is a temporary adjustment to avoid breaking debug
API users after new system routine is enabled.

This problem will be fully solved in follow up patch with switch to
zetDebugGetThreadRegisterSetProperties
