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.

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.

Avoid relying on bit-perfect irrational numbers in test code. Comparing sqrt(5) against a variable containing sqrt(5) was not working properly in some versions of Android running Vulkan.

Convert several SkSL->GLSL unit tests to golden outputs. The new test files are intended to be identical to the unit tests in every meaningful way. (Comments and formatting are not preserved exactly.) In cases where a unit-test method contained more than one test, multiple test files were created; in these cases, new names were invented to match the apparent intent of each invocation. Followup CLs will continue to migrate additional tests.
