These scripts are useful when testing WebAssembly locally
because the mimetype impacts how the binaries are loaded.
The porting was achieved by doing the following:

In this CL, I forked compile.sh and created a new gm_bindings.cpp.
I also moved viewer.html into wasm_tools and created a gmtests.html
for testing out the bindings locally.
Right now there is only one gm file compiled in. I plan in a followup
CL to have some way to generate the list of cpp files that need to
be compiled in from gms.gni. I was unable to get it to work with
simply linking the lib_gm.gni, probably due to the same issue with
Registry that csmartdalton@ ran into when adding viewer.html
and the associated bindings.
Suggested reviewing order:
- gmtests.html to get a sense of how the test flow works.
- gm_bindings.cpp to make sure I setup the contexts/GMs correctly.
- compile_gm.sh to see how the gms are compiled in.
- The remaining files in any order.
When I tested this locally, the bleed_downscale digest was
exactly the same (pixel for pixel, byte for byte) as a known
digest in Gold, so I'm fairly confident in how things work.

I don't think we need the extra bin folder; we should be
able to declare our types all in index.d.ts.
This also checks in the package-lock.json, now that we
have devDependencies to run those type checks.
`make typecheck` runs the typecheck tests.
The tsconfig.json and tslint.json were created following
the instructions at https://github.com/microsoft/dtslint
and using the DefinitelyTyped rules.

There was a break that was solved by adding -lGL to our link
steps. I discovered a few extra flags to aid in debugging builds
and I've left those in (they aren't too noisy IMO).
This changes the base dockerfile to use the official emscripten one.
Code size delta for full build is +5 kb
For future reference, emsdk decides which "library JS" files to
pull in using a83ba99d60/tools/building.py (L1553)
Those JS files live in src (e.g. a83ba99d60/src/library_html5_webgl.js (L222))
and define functions that the C++ code can call.
I'd like to follow-up on what -lEGL is doing.
Also, since the new image no longer has depot_tools, we need
to make docker/skia-wasm-release/Dockerfile install it.

> Enable skia picture effect deserialization in all flavours of build
> except for "npm" variant. If you don't have effect deserialzation enabled
> then when you try to deserialize a skp into SkPicture using canavskit

>
> On npm build effects are still being dropped if you use skia picture
> this is being done intentially to not increase the size of canvaskit wasm and

The `experimental_simd` build target builds
CanvasKit using the Emscripten `-msimd128` flag, to build CanvasKit
with SIMD instructions in the compiled WASM. This build of
CanvasKit works in Chrome Canary 86.0.4186.0
with chrome://flags#enable-webassembly-simd enabled.
Also add WebAssembly-specific intrinsics to SkVx.h to enable
support for almost all native SIMD operations in CanvasKit WebAssmebly.
Also add a Skia/modules/canvaskit/wasm_tools/SIMD folder which contains
build_simd_test.sh for testing whether WASM SIMD intrinsics operations
are actually being used by skvx, and for testing correctness of
WASM SIMD operations. Also contains simd_float_test.cpp and
simd_int_test.cpp which serve as documentation for which operations are
correctly turned into WASM SIMD operations by emscripten.

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`.

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

This can hopefully be the starting point for future work on bringing
viewer to CanvasKit.
