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.

c1d0898d0a [canvaskit] Handle 4x4 matrix passing ourselves.
This reduces the skm44_concat benchmark from 2us to .35us, a 5x
speedup.

SkCanvas.concat now takes a 3x2, 3x3, or 4x4 matrix and upscales
them all to 4x4. This makes concat44 redundant.

Removes redundant null checks for matrices, since freeing(0)
in WASM is fine like it is in C++.

6bffe39c98 [canvaskit] Handle passing matrix values into CK ourselves.
This means we take DOMMatrix everywhere now.

This reduced the *_makeShader benchmark by ~25% (4 us -> 3 us)
and cleaned up several callsites.

Trimming this down saves ~3kb in uncompressed code size.

1fa54044ef rm CanvasKit.HEAPU8.buffer caching (fix UAF bug).
Cached references to the WASM heap buffer are invalid following memory growth:
https://github.com/emscripten-core/emscripten/issues/6747#issuecomment-400081465.
This change replaces references to the cached CanvasKit.buffer with direct
references to CanvasKit.HEAPU8.buffer.  The symptom of this bug is a Javascript
error thrown in the Chrome console: "Uncaught TypeError: Cannot perform
Construct on a neutered ArrayBuffer", causing the operation in question to fail.

Bug: NONE
