Update folding tests to return pass/fail status. A passing test returns solid green. Failing tests are written to return solid red, but drawing any other color than green can be interpreted as a test failure. Additionally, tests which cannot compile as RuntimeEffects (due to non-ES2-compatible features) have been split into an ES2-compatible part and an ES3 part.

Support half4 return values from main() in the SPIR-V code generator. This creates a helper function, _entrypoint, which invokes main() and assigns its result into sk_FragColor. We also make sure to prevent sk_FragColor from being dead-stripped from the code during IR generation. At present this is useful for allowing our SkSL test shaders to compile.

Add helper uniforms to Runtime Effect tests. This lets us use descriptive names like `colorRed` and `colorGreen` instead of `half4(1,0,0,1)` and `half4(0,1,0,1)`. It also lets us use actual unknown values instead of synthesizing sorta-kinda-unknowns by calling sqrt.

Remove 0/x arithmetic simplification. If x is a known compile-time constant value, it can already be optimized to a final value. If x is not known, it could be zero, and 0/0 should result in a NaN.
