Use SkAndroidCodec in SkAnimatedImage
Bug: b/63909536
Bug: b/63908092
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.
