9be7683222 Support integer uniforms in CanvasKit runtime effects
These were added to SkRuntimeEffects, but we need to do a bit of fixup
in the CK bindings. Note that 'getUniformFloatCount' is now poorly
named, but the idea still stands: it's how many total scalar values are
required.

91292e9482 Runtime Effects: Support 'uniform shader' (vs. 'in shader')
The previous behavior leaked Skia-internal concepts into public SkSL.
Users coming from GLSL will expect that bindable/sampleable objects are
uniform (just like texture2D). This keeps the old support around (and
tested), but updates all of our examples to use 'uniform'.

54c1b3dd43 [canvaskit] Remove Sk from nearly all function/type names.
This is a massive breaking change for all existing users of CanvasKit.

It will be (one of the only) changes in 0.19.0 to make the transition
easier.

Suggested reviewing order:
 - index.d.ts (to see type changes). Notice SkPicture still has Sk
   prefix, but no other types do (this felt "right" since Sk is
   part of the name of the type, but I can be swayed on this).
 - canvaskit-wasm-tests.ts
 - tests/*.spec.js
 - interface.js and helper.js
 - html examples
 - markdown files

767f444feb SkRuntimeEffect SkSL has a new signature for main()
There is no more 'inout half4 color'. Effects return their output color.
If an effect wants the input color, it must use the (already existing)
approach of sampling a nullptr input shader.

The change is guarded for Chromium (so we can update their runtime color
filters in skia_renderer.cc).

For the GPU backend, FPs can now override usesExplicitReturn to indicate
that their emitCode will generate a return statement. If that's true,
then writeProcessorFunction doesn't inject the automatic return of the
output color, and emitFragProc will *always* wrap that FP in a helper
function, even as a top-level FP. GrSkSLFP opts in to this behavior, so
that the user-supplied return becomes the actual return in the FP's
emitCode.

Adapting the skvm code to this wasn't too bad: It looks fragile (what
happens if there are multiple returns?), but that's not really possible
today, without varying control flow.

cc8a76f3c7 [canvaskit] Add gm helper functions to tests.
Note to the reviewer: Look at tests/util.js first and then
look at the others. Gerrit lets you ignore whitespace changes,
which I would recommend for this.

This emulates tests on the C++ side and dramatically reduces
boilerplate on the test code.

This also uses the beforeEach(async () => {}) trick to save
a lot of promise resolutions before each tests.

I try to clean up the style a bit as I go, seriously thinking
about adding eslint for at least the tests.

6bffe39c98 [canvaskit] Handle passing matrix values into CK ourselves.
This means we take DOMMatrix everywhere now.

This reduced the *_makeShader benchmark by ~25% (4 us -> 3 us)
and cleaned up several callsites.

Trimming this down saves ~3kb in uncompressed code size.
