There's the barest hint of a "font manager" here.
Basically, nothing smart to deal with bold or fallbacks.
Maybe one day, we'll expose
SkTypeface* matchStyleCSS3(const SkFontStyle& pattern);
and do smart things for fallbacks, but for now that's not
in the immediate future.

While working on this, I realized some things I did
caused winding to be inconsistent with what the Canvas
spec said (and with what Chrome did).
This CL includes 2 changes to remedy that:
- removal of the subpath (which added needless complication).
- re-write of ellipse() (to mirror Chrome's implementation).

This is similar to how Chrome does it - more or less unapplying
the matrix as it changes to keep everything in the same
coordinate space.
We still need to keep the matrix around for things and do the math
ourselves for things like gradients.
This simplifies a bunch of logic, which makes me happy.

- Replace sk_memory_order with std::memory_order.
- Remove SkAtomic<T>.
SkPath was the only user of SkAtomic<T>, for its fConvexity and
fFirstDirection fields. I've replaced them with std::atomic types, and
funneled access to them through methods that enforce the relaxed memory
order like SkAtomic<T> did.
For fConvexity, we can use the exisiting setConvexity() and
getConvexityOrUnknown() methods, adding a private const setConvexity()
to mutate convexity from const methods. For fFirstDirection I've added
private setFirstDirection() and getFirstDirection() methods.
Removing SkAtomic<T> means SkAtomics.h no longer needs SkNoncopyable.h.
I've had to update a bunch of other headers that were depending on
transitive inclusion.

These changes expose the arc function for SkPath. The ApplyAddArc function is a copy from the PathKit bindings.
Also exposed the PNG and JPEG formats from the SkEncodedImageFormat enum and the SkImage::encodeToData overload that accepts format and quality options. The direct binding of encodeToData was replaced with a pre-js wrapper that calls the appropriate private overload
We are working on a PostCSS conic gradient polyfill plugin and want to use the CanvasKit to generate it.
Problem is - it lacks the arc function that technically exists but isn't exposed. And it would be really great to have encodeToData with options since generated PNGs are quite large.

I can probably write most, if not all, of a Canvas API in
JS using the SkCanvas and SkPaint objects. This lets us expose
the fancier API and optionally have a more familiar API.
This is controlled at compile time, i.e. bring in the extra

There is still plenty of the API that needs working, but
this is meant to outlay the plans of where this is going.
