Use spirv-tools optimizer in GraphicsPipeline

Run some optimization passes before lowering the code, to allow for a
simpler compiler.

Current passes:
- Exhaustively inline functions
- Apply and freeze specialization constants

I expect this set of passes will change somewhat as the
compiler evolves. We may want to stop inlining at some point.
