Re-enable SkSL tests in CanvasKit/wasm.

We can disable SkSL tests on a case-by-case basis via the skip list in
`run-wasm-gm-tests.html`. This doesn't allow us to exclude by GPU, but
in practice the Golo machines tend to all have a uniform setup (with
Quadro P400s) so we can just work around failures as they come up.
