John Stiles da5cdf6a70 Add default uniform binding value for Metal/SPIR-V.
This allows interface blocks in Metal to compile even if
`layout(binding=...)` is not specified. It will also be used in SPIR-V
in the followup CL, when an interface block is automatically synthesized
for top-level uniforms.

This CL also reorganizes the unit tests around uniforms a bit.
