Change sksl tests to avoid SPIR-V validation errors 'in' variables without locations aren't allowed. Use uniforms instead.

Implement compile-time optimization for refract(). $genType refract($genType I, $genType N, float eta); $genHType refract($genHType I, $genHType N, half eta); The half form of refract was originally taking a `float eta` in our headers, which seems wrong (and causes the DSL to break unless you add casts). I've corrected the headers to use `half eta`.
