One immediate use-case for this is running tests when SSH'd into a
remote machine. In theory, X11 forwarding could be used to forward the
remote Chrome UI. In practice, Chrome is difficult to forward
correctly, and the options for doing so are empirically quite slow. In
testing, forwarding from Ubuntu to Mac required passing
--use-gl=swiftshader to Chromium, and rendering was slow enough to
timeout tests.

Changes are largely mechanical. Non-mechanical changes to support newer
versions of emscripten are enumerated below, in format ${EMSCRIPTEN_VERSION}:
${RELEVANT_CHANGE}.
- 1.39.9: TOTAL_MEMORY has been renamed INITIAL_MEMORY.
- 1.39.12: passing of linker flags to wasm-ld has changed in a way that requires
supplying `--no-entry` to avoid error message "wasm-ld: error: entry symbol
not defined (pass --no-entry to suppress): main".
- 1.39.16: The factory function created by using `MODULARIZE` build option now
returns a Promise instead of the module instance. As such, the ready.js
workaround is removed. Note this is a breaking API change for CanvasKit,
which now uses just `then()` and not `ready().then()`.
- 1.38.33: `emsdk install` hasn't required the `-64bit` suffix on version names
since `1.38.33`, so we remove them. E.g. `emsdk install sdk-1.39.6-64bit`
simply becomes `emsdk install sdk-1.39.16`.

Adding in the mono rasterizer on freetype adds 12k of code size
(6k compressed), so we make it opt out and don't ship to npm with it.

This does a head to head comparison for our JS-implemented
SkMatrix (DOMMatrix is tens of times slower) and adds support.
There are a few APIs (e.g. on Canvas) that don't yet support this.
This is because I want to experiment with the speed difference
between SimpleMatrix and emscripten's bindings and us just allocating
an array for the user on the WASM heap.

Adds a "viewer" option to the build system that brings in tooling code
and sample code. Adds a very simple "MakeSlide" binding that knows
how to create the WavyPathText sample slide. Adds viewer.html with
code to animate viewer slides.
This can hopefully be the starting point for future work on bringing
viewer to CanvasKit.
