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.

In https://skia-review.googlesource.com/c/skia/+/291182 emscripten was updated
to 1.39.16. This introduced a breaking API change to the CanvasKit
initialization callback, which becomes simply `then()` as opposed to
`ready().then()`. In the course of this change, I missed a few `ready()` calls,
which has broken the examples in public-facing documentation.
E.g. https://skia.org/user/modules/canvaskit. This CL fixes that.

This was only being used in one effect (and for no good reason). SkSL is
plenty powerful to re-implement something similar if required, at no
real performance cost.
Re-implemented the one effect that used it with simpler math in the
script, updated the copy of that effect in the gallery.

There's the barest hint of a "font manager" here.
Basically, nothing smart to deal with bold or fallbacks.
Maybe one day, we'll expose
SkTypeface* matchStyleCSS3(const SkFontStyle& pattern);
and do smart things for fallbacks, but for now that's not
in the immediate future.

Building CanvasKit uses very similar logic to PathKit, so there
was a fair amount of copy/paste/customize.
Fixes the name of skia.js/wasm -> canvaskit.js/wasm and
adds a package.json to formally track versions.
Also move PathKit helper scripts to align better.

Breaking Changes (should be minor, as it's mostly just things
for testing):
- PathKit.ApplyPathOp should have returned a new SkPath, but didn't.
It now does and is named "MakeFromOp", which makes the convention of
"Have 'make' in name, needs delete" more consistent.
- PathKit.FromCmds(arr) now only needs to take the JS Array and
will handle the TypedArrays under the hood. If clients want to deal
with TypedArrays themselves, they can use _FromCmds(ptr, len) directly.
- PathKit.MakeLTRBRect is now just PathKit.LTRBRect. The thing
returned is a normal JS Object and doesn't need delete().
As per custom with v0 apps, we are updating the minor version
to v0.3.0 to account for breaking changes.
