This new tessellator renders strokes as fixed-count triangle strip
instances. Any extra triangles not needed by the instance are emitted
as degenerate triangles. Since it draws in order, this tessellator
allows us to batch dynamic colors even when hw tessellation is not
supported.

These enforce stricter rules about the signature of main, and each one
uses a separate pre-include module. That prevents color filters from
being able to reference sk_FragCoord (or coords passed to main) at all.
It also limits the versions of sample() that are exposed.
In the new world, an effect created for a specific stage of the Skia
pipeline can only be used to create instances of that stage (SkShader or
SkColorFilter). For now, SkRuntimeEffect::Make uses kRuntimeEffect,
which continues to be more lenient and allow creation of either shaders
or color filters from a single effect. After we migrate all clients, we
can deprecate and then delete that mode.

For now, just bolt this onto the existing runtime effects. The next step

Our benchmarks had drifted away from actual codegen in several ways, and
were no longer representative of actual output. In particular, every
function in the existing benchmarks used a scratch `_output` variable
which would make it ineligible for return-statement-only inlining.
Updated the tests to match modern codegen. `small` and `large` use the
same sources as before. The code from `medium` is older and had diverged
quite far from today's output; I could not find a representative code
snippet at all. It has been replaced with SkSL of roughly similar
complexity.

This is useful because it allows the variables to be declared as `const`
when they are trivial values like `half4(1)`. This enables the constant
folder to simplify or eliminate them. In most cases, this is only a
small benefit, as you'd expect a competent GPU driver to do the same.
However, Mali-400 can benefit significantly from optimizing away the
multiplication against a constant half4(1) coverage in Porter-Duff.
