Reland "[canvaskit] Change SkRects to be arrays, not objects."

Browse Source 
This is a reland of bdc214a50e

The CPU version of SkottieWasm is timing out for reasons unknown,
but the GPU version is happy. I think we can get rid of the CPU
version of the job since it has been more or less superseded by
the SkottieFrames one (and the latter is more stable).

Original change's description:
> [canvaskit] Change SkRects to be arrays, not objects.
>
> This changes several APIs, so there are lots of breaking
> notes in the Changelog.
>
> This made the "draw 100 colored regions" benchmark about
> 20% faster (1ms -> .8ms).
>
> In theory, rendering should stay the same.
>

## [Unreleased]
### Breaking
- SkRect are no longer returned from `CanvasKit.LTRBRect`, `CanvasKit.XYWHRect` nor
are accepted as JS objects. Instead, the format is 4 floats in either an array, a
Float32Array or a piece of memory returned by CanvasKit.Malloc. These floats are the
left, top, right, bottom numbers of the rectangle.
- SkIRect (Rectangles with Integer values) are no longer accepted as JS objects.
Instead, the format is 4 ints in either an array, an Int32Array or a piece of memory
returned by CanvasKit.Malloc. These ints are the left, top, right, bottom numbers of
the rectangle.
- SkRRect (Rectangles with rounded corners) are no longer returned from `CanvasKit.RRectXY`
nor accepted as JS objects. Instead, the format is 12 floats in either an array, a
nor are accepted as JS objects. Instead, the format is 12 floats in either an array, a
Float32Array or a piece of memory returned by CanvasKit.Malloc. The first 4 floats
are the left, top, right, bottom numbers of the rectangle and then 4 sets of points
starting in the upper left corner and going clockwise. This change allows for faster
transfer between JS and WASM code.
- `SkPath.addRoundRect` has been replaced with `SkPath.addRRect`. The same functionality
can be had with the `CanvasKit.RRectXY` helper.
- `SkPath.addRect` no longer accepts 4 floats as separate arguments. It only accepts
an SkRect (an array/Float32Array of 4 floats) and an optional boolean for
determining clockwise or counter-clockwise directionality.
- The order of `SkCanvas.saveLayer` arguments is slightly different (more consistent).
It is now `paint, bounds, backdrop, flags`
### Changed
- We now compile CanvasKit with emsdk 2.0.0 when testing and deploying to npm.

- The signature of `main` used with SkSL passed to `CanvasKit.SkRuntimeEffect.Make` has changed.
There is no longer an `inout half4 color` parameter, effects must return their color instead.
Valid signatures are now `half4 main()` or `half4 main(float2 coord)`.
- `SkPath.getBounds`, `SkShapedText.getBounds`, and `SkVertices.bounds` now
take an optional argument. If a Float32Array with length 4 or greater is
provided, the bounds will be copied into this array instead of allocating
a new one.
### Removed
- `SkCanvas.drawRoundRect` has been removed in favor of `SkCanvas.drawRRect`
The same functionality can be had with the `CanvasKit.RRectXY` helper.
- `SkPath.arcTo` which had been deprecated in favor of `SkPath.arcToOval`,
`SkPath.arcToRotated`, `SkPath.arcToTangent`.
### Added
- `CanvasKit.LTRBiRect` and `CanvasKit.XYWHiRect` as helpers to create SkIRects.
