The previous version accidentally retrieved all values from
the in memory glyph cache because it was always measuring
the range 1-300. This changes the glyphID to always be an
increasing number, which avoids the cache hits.
There is now some differences between the font types:
- ttf: ~4ms
- woff: ~160ms
- woff2: ~230ms
The high numbers in the woff categories are expected to be
fixed by https://skia-review.googlesource.com/c/skia/+/420578

As is, all 3 formats have a median time of about 0.12 milliseconds.
Perhaps the performance hit is more strongly felt on larger font
files.

This is a massive breaking change for all existing users of CanvasKit.
It will be (one of the only) changes in 0.19.0 to make the transition
easier.
Suggested reviewing order:
- index.d.ts (to see type changes). Notice SkPicture still has Sk
prefix, but no other types do (this felt "right" since Sk is
part of the name of the type, but I can be swayed on this).
- canvaskit-wasm-tests.ts
- tests/*.spec.js
- interface.js and helper.js
- html examples
- markdown files

I added 3 tests, one using the drawRect API naively,
one using drawRect with a Malloc'd array, and one using
the drawRect4f.
rough local measurements:
- [baseline with tip of tree code]: 50ms
- naive drawRect: 40ms
- drawRect with malloc: 28ms
- drawRect4f: 27ms
I also tried the benchmarks locally with taking in paint
as a const reference. I did not see any changes, but that
could just be small sample size. I plan to land the code
as is for now, collect a bit of data in Perf and then try
landing the const reference stuff and see if we get
something measurable.
To aid this, I added in a helper list of tests to only run
some benchmarks easily.
