feat(tc): add default SLC policy for the gpu

Browse source 
As per the GPU integration guide, adding the PBHA INT overrides to
influence the GPU allocation policy for the System Level Cache (SLC).

This commit uses SLC policy , which is the Arm SLC cache policy
number for GPUs. The cache policy  may not be optimal for all
workloads, although it outperforms other policies on the tested data
sets.
