dffd20efe9 [canvaskit] Add unit tests to wasm_gm_tests
There are currently many tests skipped, but many more pass.
This changes the built binary to have a lot of debugging logic
in it so we should be able to get backtraces on those crashes
more easily when debugging.

gmtests.html was removed as it was superceded by run-wasm-gm-tests
and make run_local.

acdc283404 [canvaskit] Use portable fonts for GMs
This adds an Init() which should be called before any resources
are loaded or GMs/Tests are called.

This also adds a little helper in compile.sh for building only
a single GM, which can make local development faster given the
fact that emsdk doesn't do its final compilation/linking in
parallel.

bffc116a4a [canvaskit] Load resources into wasm gms/unit tests.
To load in the resources, we have the Node JS script
find all files in the provided resources directory and serve
that as a JSON file (the HTML JS can't list files easily).
The HTML JS reads that file, then loads all those files as
ArrayBuffers.

After the testing WASM and the resources all load, we pre-load
them into the WASM memory, assigned with their name. This is
just a map of name -> SkData. The WASM code can't (easily)
make fetch calls, so rather than load these resources on demand
like we would in a real file system, we pre-load them all
and serve them from RAM. For simplicity (and consistency with
the known_hashes), this map is a global.

Finally, to connect the resources to the GMs, we overwrite the
gResourceFactory (defined in ResourceFactory.h) which is used
by tools/Resources.cpp to load any resource file (in theory).

One more change is to write some progress steps to window._log
so it can be read by puppeteer and dumped to disk to aid in
debugging.

a25c0619b5 [canvaskit] Make gm test wrapper not omit known pngs
We just make a global set of known png digests and expect that the test
harness will load this with the appropriate data.

0039874105 [canvaskit] POC bindings for testing gms
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.
