Migrate several GLSL workaround unit tests to golden files. We now support building an SkSL golden output twice, once honoring the custom #pragma settings, and once more ignoring the settings. This allows us to see the output of the workaround technique, alongside the "default-settings" output which should not contain a workaround. To implement this, skslc now supports a flag: --[no]settings. When it's set, /#pragma settings/ comments are honored. When it's not set, skslc ignores the comments. compile_sksl_tests.py passes this flag along to skslc. This approach is not strictly limited to workarounds; the "TypePrecision" GLSL test was also updated to use this technique.

Update tests which mix int and float types without casts. These need to change because type coercion in SkSL is about to become more strict in a followup CL; we are disallowing expressions that mix ints and floats without a cast.
