[PathKit] Add asm.js build and test jobs
Consolidates the karma files into one for docker/asmjs/wasm and all
combinations.
The asm.js build seems to have some small imprecisions that we didn't
see as much as with WASM, probably due to JS limitations/differences
to c++'s floats.
To address these, I've marked some (5) tests in PathOps* as flaky
because they fail on Release, Debug or Test versions of the asm.js build.
Other then that, asm.js seems basically identical to the WASM.
WASM is much smaller, 416k vs 877k and seems to load faster (not
measured).
Note to reviewers:
example.html was copied from npm-wasm version, so doesn't need
further review.
