John Stiles 72664bede4 Add support for #pragma settings comments in SkSL.
This will allow us to write skslc-based golden tests that deviate from
the standalone skslc settings.

This CL provides six options; more will be added as necessary.
- Default (caps)
- UsesPrecisionModifiers (caps)
- Version110 (caps)
- Version450Core (caps)
- ForceHighPrecision (settings flag bit)
- Sharpen (settings flag bit)
