This keeps punning things to premul (in anticipation of pulling
back on any unpremul support outside read/write/scalePixels),
and yet still clamps correctly for scalePixels() + unpremul + HQ
and/or gamut transform.

>
> So we extend SkImageShader's internal API to allow specifying an output

SkAnimatedImage is designed around a specific Android use case, so move
it into the android folders.
Make SkAnimatedImage hold an SkAndroidCodec (instead of an SkCodec).
Expose fCodec so that SkAnimatedImage can animate by using the internal
SkCodec.
Update the sample to use SkAndroidCodec.
Allow webp to decode a scaled down animation. For RestoreBG frames,
adjust the frameRect (which is erased) to account for the scaling. Add
a test to verify that we decode a webp with a RestoreBG frame
successfully. Disable scaling for later frames in other formats (GIF,
for now), since the code for erasing a RestoreBG frame is currently
unaware of the sampling.

Bug: b/63909536
SkAnimatedImage is a simple drawable for animating a GIF. Thread-safety
is left up to the client. At most two bitmaps are stored in the
drawable; one for the current frame and one for a frame that may need to
be restored. The backup frame prevents some cases where we would
otherwise have to re-decode from the beginning of the image.
The API lets the client set the time value, and decodes to match that
time.
TODO:
- Callback for when the animation is complete
- Ability to use SkAndroidCodec
- Modify the loop count (or leave that up to client?)
- Better and/or client-specific caching
Other changes:
- Add a sample which animates a GIF
- Reenable SK_CODEC_PRINTF for debug builds and Android

After this CL, we have 3.5 options for fuzzing ImageFilter
1. Create it from API calls and then draw it
fuzz -t api -n ImageFilter -b [input]
2. Deserialize a fuzzed stream into an ImageFilter (this is
what Chromium's filter_fuzz_stub does)
fuzz -t filter_fuzz -b [input]
3. Create an ImageFilter from API calls, serialize it, apply
some mutations to the stream, deserialize it, then draw it.
fuzz -t api -n SerializedImageFilter -b [input]
3.5 Create ImageFilters as part of our more general canvas
fuzzers.
fuzz -t api -n RasterN32Canvas -b [input] (and others)
Previously, the SerializedImageFilter had its own, slightly
stale and prone to stack-overflow way of making an image filter.
This CL re-uses what we already do for Canvas fuzzing and removes
that dead code.
Additionally, there is a way to easily generate a corpus
for the filter_fuzz type, via SerializedImageFilter.

Coarse workflow:
* Construction
1) build a Json tree
2) collect asset IDs (for preComp/image layer resolution)
3) "attach" pass
- traverse the Json tree
- build an SkSG dom, one fragment at a time
- attach "animator" objects to the dom, for each animated prop
4) done, we can throw away the Json tree
* For each animation tick
1) iterate over active animators and poke their respective dom nodes/attributes
2) revalidate the SkSG dom
3) draw the SkSG dom
Note: post construction, things are super-simple - we just poke SkSG DOM attributes
with interpolated values, and everything else is handled by SkSG (invalidation,
revalidation, render).
