Currently our ANGLE vendor/renderer detection is based ANGLE's D3D
backends. To detect on the GL backend it'd be helpful to reuse the
normal GL detection after extracting the relevant GL backend strings
that ANGLE puts in GL_RENDERER in its GLES frontend. This is a step in
that direction.

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.

It was possible that multiple threads could detect that an entry did not
exist in the cache, both create a new entry, and both add to the cache.
The first to put an entry into the cache would be what subsequent
threads would retrieve from the cache.
Re-organize the code to avoid this race, make it easier to see that
typefaces created from data are not cached, and only take the mutex
once when using the cache.

Chromium has been updated to use makeAnalysisCanvas directly and there are
no more references to SkTextBlobDiffCanvas as a type in its code base.
Since the GlyphTrackingDevice extends SkNoPixelsDevice, any SkCanvas that
uses it is effectively a "no-draw" canvas. However, by returning a base
SkCanvas the text tracking now automatically happens in the context of
the base's AutoLayerForImageFilter handling it applies on every draw. This
means that drawing a text blob with an image filter that modifies the
transform state will now be analyzed in that context automatically
(simplifying code in chrome after this lands).
Another behavioral change is that all non-text draws will still go through
the base SkCanvas' virtuals and invoke the device function. Since it's an
SkNoPixelsDevice, it'll still be a no-op, it just happens a little later.
This won't really impact performance because oop-r already inspects their
operations and only plays back text and transform related ones to the
analysis canvas, so we shouldn't really see non-text draws being invoked
anyways.
