venus: shader cache fossilize replay fix

Browse Source 
venus utilizes the host side shader cache.

This is a WA to generate shader cache files containing headers with
a unique cache id that will change based on host driver identifiers.
This allows fossilize replay to detect if the host side shader cache
is no longer up to date.
The shader cache is destroyed after creating the necessary files and
not utilized by venus.
