Implement a simple evaluator of specialization constants.
In some cases, we need to get a literal value from a spec constant op.
Mostly relevant when emitting buffers, so implement a 32-bit integer
scalar subset of the evaluator. Can be extended as needed to support
evaluating any specialization constant operation.
