anv: Add option to disable HiZ via drirc

Browse source 
Allows per-app disabling of HiZ if a case arises where HiZ is
significantly slowing down a workload.

This option should not be the resulting fix for when such cases
arise, but can serve as a temporary band-aid while a proper
solution is fleshed out.
