This is a reland of be056f4f62
The Switch test has been restructured to dodge an iOS bug.
Original change's description:
> Add switch statement support to PipelineStage.
>
> This allows us to write SKSL_TEST_ES3 tests in SkSLTest and have them
> run properly. Previously, such a test would assert inside the pipeline-
> stage generator. In ES2 mode, we will rewrite switches as chained ifs,
> but in ES3 mode we will want to continue emitting them as-is (they will
> be faster than chained ifs on a modern GPU).
>
> `writeSwitchStatement` is adapted from GLSLCodeGenerator.
