We only break runs (from the shaper's perspective) on typeface/size
changes. All others we just track locally, and then 'chop up' our draws
accordingly.

Known hacks for now:
- only default typeface
- only ascii support
Fonts have several limitations for now.
SkParagraph (our temporary backend) wants a fontmgr up front,
rather than just relying on the typefaces in its styles. This makes it
hard to inter-op with our JS api. Not a long-term problem, as this
backend is short-term. The hacky work-around is just to pass NULL for
the typeface for now.
Related but different, I haven't yet figured out how to "return" a
JS Typeface object. Something about bare-pointers and sk_sp. I'll figure
it out eventually, but for now I just set the output slot to null
as well. (there's a TODO in the .cpp)
Ascii support
JS strings are UTF16 (afaik). However, our current backend thinks in
terms of UTF8 offsets. Plus, (at the moment) when I try to access the
JS string for C++, it coerces to utf8 (std::string).
We can fix both of these eventually, but for now I'll just test with
ascii input characters, and the API can still work.

1. Fold "origin" into the positions (simplification)
2. Extend positions and offset arrays by 1, to include 1-past last glyph
3. Add flags field to run (with just WS flag for now)

This is another strange, experimental feature that clutters the
implementation and isn't used by anyone (to my knowledge).

Font was missing getMetrics()
However, seems like getShapedRuns() needs to return its
particular line spacing choices...

Only text string + size for now, we can surface more if needed.

Also rename //modules/canvaskit/canvaskit to //modules/canvaskit/npm_build
to make it more clear the purpose of that folder (what we ship to
npm and stage our builds for local testing).
