John Stiles 0ed9f31f6a 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.
