By setting the compile time flag:
SK_EXPERIMENTAL_SIMULATE_DRAWGLYPHRUNLIST_WITH_SLUG_STRIKE_SERIALIZE
will cause all SkTextBlobs to be rendered by analyzing the Slug
to create strike cache differences and serialize the Blob to a Slug.
Then the serialized strike cache differences are used to populate
the strike cache using a different TypefaceIDs using SkTypeface_Remote
as a proxy for the real SkTypeface. This will create a hard break
between the original glyph data, and the proxied glyph data.
It will then deserialize the Slug doing TypefaceID translation to
the SkTypeface_Remote, and draw the unflattened Slug.

This failure happens when using the SkRemoteGlyphCache system
*and* serializing slugs. The problem is that the origin from the
blob conversion was applied twice causing all the sub-pixel
positions to be off. This often pass because this position often
is {0, 0}.

A glyph cache entry is made up of metrics, an image, and a path. If an
entry does not exist then nothing is known of the glyph yet. If there is
an entry it must have at least the metrics. The image and the path may
logically be added lazily as needed. Prior to this change it was not
possible to send both the image and the path of a single glyph. The
added test fails when a given strike is used for both the image and the
path. With this change the test passes, as the image is sent and the
path is sent, and both are merged into the remote glyph. The assertions
around not creating the glyph more than once are replaced with
assertions that no part of the glyph is set more than once.

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.

`const` on a non-pointer/reference return type typically doesn't add
value and can have negative side effects. (i.e., returning a
`const std::string` isn't meaningfully different from returning a
`std::string`, but can sometimes inhibit move-related optimizations.)
In Skia's case, the priv() functions are a notable exception where const
return types are intentional and valuable. These calls have been marked
with NOLINT to exclude them from the check.
This check does not affect pointer and reference returns, where
constness is important.
