f8823b5726 Reland "[canvaskit] Change SkRects to be arrays, not objects."
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version of the job since it has been more or less superseded by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).

bdc214a50e [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.

3f45e4b322 [skottie] Custom prop manager updates
Currently we use a hard-coded name prefix ('$') and the properties are
"namespaced" (the tree hierarchy is part of the key name).

This doesn't work well for most clients looking to test property
manipulation, as they would rather handle similarly named props in
bulk.

E.g. instead of

  precomp1.layer1.Group1.COLOR_01
  precomp1.layer1.Group1.COLOR_02
  precomp1.layer2.Group1.COLOR_01
  precomp1.layer2.Group2.COLOR_02

the UI should simply present

  COLOR_01
  COLOR_02

To support this, introduce a new operation mode for
CustomPropertyManager (kCollapseProperties), and keep the old behavior
around as kNamespacedProperties.

Also drop filtering for markers as anyone interested in markers would
want to see all of them.

Plumb these options all the way into CK (to be added to the player
later).

69e46da716 [canvaskit] Fix infrequent crash in SkFontMgr.FromData
The bug here is very subtle, as is the mitigation.

Quick background on WASM memory, there is an object
called wasmMemory (which might be hoisted into scope for
CanvasKit's pre-js functions), of type WebAssembly.Memory
which is a resizable ArrayBuffer. Emscripten provides the
JS code to initialize this and handle size increases.
Emscripten also provides TypedArray "views" into this buffer.
These are called CanvasKit.HEAPU8, CanvasKit.HEAPF32, etc.

When there is a call to CanvasKit._malloc, wasmMemory may
be resized. If that happens, the previous TypedArray views
become invalid. However, in the same call to _malloc,
emscripten will refresh the views [1]. So, dealing with
CanvasKit.HEAPU8 directly (quick aside, we never expect clients
to mess with these views, only us in our glue JS code
[e.g. interface.js]), should always be safe because if they
were to be invalidated in a call to _malloc, the views would
be refreshed before _malloc continues.

The problem that existed before was when we were passing
CanvasKit.HEAP* as a parameter to a function, in which the
function would call _malloc before using the typed array
parameter:
  //... let us suppose wasmMemory is backed by ArrayBuffer D
  copy1dArray(arr, HEAPU32);
  // The HEAPU32 TypedArray (backed by ArrayBuffer D) is stored
  // to a function parameter "dest"
    function copy1dArray(arr, dest, ptr) {
    // ...
    if (!ptr) {
      ptr = CanvasKit._malloc(arr.length * dest.BYTES_PER_ELEMENT);
      // Suppose _malloc needs to resize wasmMemory and is
      // now backed by ArrayBuffer E.
      // Note: The field CanvasKit.HEAPU32 is correctly backed
      // by ArrayBuffer E, but variable dest still points to a
      // TypedArray backed by ArrayBuffer D.
    }
    // dest.set will fail with a "neutered ArrayBuffer" error
    // because ArrayBuffer D is effectively gone (replaced by E).
    dest.set(arr, ptr / dest.BYTES_PER_ELEMENT);

The fix here is to pass in the field name indicating the TypedArray
view we want to write our data into instead of using the
view itself as the parameter.

6aa3869f76 [canvaskit] Use scratch arrays for colors and matrices
At startup, we allocate a few scratch arrays and then use those
instead of having to malloc and free a bunch of arrays during
runtime.

The benchmark that was added is a bit noisy (probably because
of the garbage collection going on from the created Float32Arrays),
but a few percent faster.

We also don't set the paragraph background/foreground colors to
transparent because we check them being falsey before sending them
over the wire. I noticed that if foreground was transparent black,
no text shows up at all, which was unexpected.

cf11892ab2 [canvaskit] Do not automatically free things provided by Malloc.
If ever CanvasKit accepts an array as a parameter, if the array
provided was produced by Malloc, CanvasKit will use the pointer
of that array and not free it after.
