The drawGlyphs implementation seems to have a 20-30% performance
edge and drawText is a few percent slower than fillText on my
machine.

There are two approaches taken - naively using a bunch
of drawTexts and using drawGlyphs. The latter runs about
twice as fast (45 ms per frame vs 90 ms per frame) at the
expense of more complex code (need to layout individual
glyphs in the JS).

This creates a new SkImage with the same texture and changes it
out without the user noticing (or needing to delete the old Image).

Before we get too excited, this does not use CanvasKit.
What this does add is an origin-trial token so we can
more easily demo our progress on *.skia.org and test
locally using localhost:8123 (which is the default
if you run make local in //demos.skia.org)
To view this locally, I started chrome (stable 94) with
--enable-features=Vulkan --enable-unsafe-webgpu
Enabling the Vulkan was the advice of
https://web.dev/gpu/#browser-support
The second flag make sure the whole stack also uses Vulkan.

This includes a helper Surface.makeFromTextureSource that will
make the gl calls with some sensible defaults.

We should encourage users to use a real CDN, not a random build of ours.
This also fixes a few broken demos.

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

In this demo the user may choose between one of three path rendering methods
1. SVG
2. Canvas2D Path2D API
3. CanvasKit
SVGs is animated using css transforms on the main thread, while Canvas2D and CanvasKit are animated
in a worker using OffscreenCanvas.
While the user views the result of the rendering, the demo collects framerate data and displays it
so the user may compare the performance of the three methods.
