GPU: disable compute shader for problematic drivers 

Some drivers for legacy platforms seem to have issues with compute
shaders, as revealed by T94936. This disables compute shader for the
known drivers where this issue is present. It is not clear if the issue
is Windows only or not, so this disable them for all operating systems.

See T94936 for a list of configurations where the issue is reproducible
or not.
