Difference [1]:
The mask is added to the masks above it in the stacking order. In
areas where the mask does not overlap the masks above it, the mask
operates as it would alone on the layer. In areas where the mask
overlaps the masks above it, the influence of the mask is subtracted
from the masks above it.

Although it appeared that the experimental_simd CanvasKit build was
working, the build was not producing actual wasm SIMD operations. This
CL fixes that issue by changing the build arguments.
This issue also fixes an incorrect type issue with the SkVx wasm SIMD
implementation.

Two issues:
1) For static keyframes (start_value == end_value) AE yields horizontal
orientation (0 tangent). We technically have the same logic in
Skottie, but our value deduplication logic interferes: the two
consecutive equal values are consolidated, and the result ends up
holding the spatial lerp info for the next frame => our hold frames
auto-orient for the beginning of the next keyframe.
Fix: skip value deduplication when spatial lerp is present.
2) The very last keyframe is always static and holds no spatial info.
AE retains the orientation of the previous frame, but Skottie yields
0 tangent.
Fix: the easiest way to accomplish AE semantics is to detect when
we're dealing with the last keyframe, and swap with the previous
keyframe with an adjust weight of 1 (to select the end value). This
produces the same lerp result (because keyframed values are always
contiguous) and also respects the orientation of the prev frame.

AE allows animating the line spacing text property [1].
Observed semantics:
- spacing is applied as an offset to all fragments in a line
- for selector/partial coverage, the spacing for a given line
is the average of the computed spacing for each fragment
- spacing is cumulative (applies to all lines following)
Plumb the new animator prop ("ls") and expand the existing line
tracking logic to also apply computed spacing offsets.
(also requires a Bodymovin update to export the line spacing property)

Also add WebAssembly-specific intrinsics to SkVx.h to enable

Also add a Skia/modules/canvaskit/wasm_tools/SIMD folder which contains
build_simd_test.sh for testing whether WASM SIMD intrinsics operations
are actually being used by skvx, and for testing correctness of
WASM SIMD operations. Also contains simd_float_test.cpp and
simd_int_test.cpp which serve as documentation for which operations are
correctly turned into WASM SIMD operations by emscripten.

https://skia-review.googlesource.com/c/skia/+/297896 draws
several paths with over 1000 points (one has ~250k) and
was pretty slow. We already had a way to provide a flat(ish)
array of all the verbs, points and weights mushed together
(although that should be cleaned up to prefer taking a 1d
array).
This adds an additional way to provide multiple verbs,
points, (and optionally weights, if conics are used) to CanvasKit.
This makes things dramatically faster because of batch copying
the values between JS and WASM (or using Malloc).
Additionally, the above CL revealed a need to be able to
use a subsection of a Malloc'd array efficiently. Thus,
I added subarray as a method of the Malloc object, which
can be used effectively as a pointer (i.e. no copying).

CanvasKit.MakeImageFromEncoded, when used with Browser APIs for loading/decoding images.
- `CanvasKit.MakeImageFromCanvasImageSource` takes either an HTMLImageElement,
SVGImageElement, HTMLVideoElement, HTMLCanvasElement, ImageBitmap, or OffscreenCanvas and returns
an SkImage. This function is an alternative to `CanvasKit.MakeImageFromEncoded` for creating
SkImages when loading and decoding images. In the future, codesize of CanvasKit may be able to be
reduced by removing image codecs in wasm, if browser APIs for decoding images are used along with
`CanvasKit.MakeImageFromCanvasImageSource` instead of `CanvasKit.MakeImageFromEncoded`.
- Three usage examples of `CanvasKit.MakeImageFromCanvasImageSource` in core.spec.ts. These
examples use browser APIs to decode images including 2d canvas, bitmaprenderer canvas,
HTMLImageElement and Blob.
- Added support for asynchronous callbacks in perfs and tests.
Here are notes on the image decoding approaches we tested and perfed in the process of finding ways
to use Browser APIs to decode images:
1. pipeline:
ArrayBuffer → ImageData → ctx.putImageData →
context.getImageData → Uint8Array → CanvasKit.MakeImage
❌ Problem: ImageData constructor expects decoded bytes already.
2. interface.js - CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded (async function)
pipeline:
ArrayBuffer → Blob -> HTMLImageElement ->
draw on Canvas2d -> context.getImageData → Uint8Array →
CanvasKit.MakeImage
✅ Works
⏱ Performance: 3rd place (in my testing locally)
3. interface.js - CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded2 (async function)
ArrayBuffer → Blob → ImageBitmap → draw on Canvas2d →
context.getImageData → Uint8Array → CanvasKit.MakeImage
✅ Works
⏱ Performance: 2nd place (in my testing locally)
4. interface.js - CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded3 (async function)
ArrayBuffer → Blob → ImageBitmap →
draw on canvas 1 using bitmaprenderer context →
draw canvas 1 on canvas 2 using drawImage → context2d.getImageData →
Uint8Array → CanvasKit.MakeImage
✅ Works
⏱ Performance: 1st place (in my testing locally) - quite surprising, this in some ways seems to be a more roundabout way of CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded2, but it seems bitmaprenderer context is fairly fast.
