nir: Add a NIR_VALIDATE environment variable
It defaults to true so default behavior doesn't change but it allows you to
do NIR_VALIDATE=false if you don't want validation. Disabling validation
can substantially speed up shader compiles so you frequently want to turn
it off if compiler invariants aren't in question.
