d9b9e5ec4b [canvaskit] High performance Path APIs
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).

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.

cc8a76f3c7 [canvaskit] Add gm helper functions to tests.
Note to the reviewer: Look at tests/util.js first and then
look at the others. Gerrit lets you ignore whitespace changes,
which I would recommend for this.

This emulates tests on the C++ side and dramatically reduces
boilerplate on the test code.

This also uses the beforeEach(async () => {}) trick to save
a lot of promise resolutions before each tests.

I try to clean up the style a bit as I go, seriously thinking
about adding eslint for at least the tests.

79b7134b5f [canvaskit] Add relative SkPath operators
Like with the non-relative forms, we want to be able to
chain these together, but not leak the SkPaths (which happens
if the C++ side returns this). Thus, we have to add in
the JS glue to return the "JS this".
