Bug: 78866720
The client in Android calls newPictureSnapshot, which results in copying
the mutable SkBitmap into a newly allocated one in each frame. Avoid
this by calling SkMakeImageFromRasterBitmap with
kNever_SkCopyPixelsMode. Make SkAnimatedImage copy on write, by copying
before decoding if the bitmap's pixel ref is not unique.
Android's AnimatedImageDrawable's current architecture only decodes one
frame in advance, so it will never need to perform the copy on write.
This will save one bitmap allocation per GIF frame.
Add a test to verify that copy on write works as expected.

Rather than keeping track of the time and whether the animation is
running, leave that up to the client. Offer a single method to decode
the next frame, allowing the client to stay one frame ahead.

Android does not need to have its end listener attached if the
repetition count is infinite. Provide an accessor so it will know.

By default use the repetition count stored in the encoded data (if
any). Allow setting the repetition count manually, so that the
animation will stop after n+1 total cycles (unless -1 is used for
infinite).
If the animation is complete, make start reset it.
When the animation is not running, make update return max double (i.e.
no need to update any time soon).
Fix a bug where the first call to update returned -1.
Share write_bm with CodecAnimTest, for debugging.
Update Sample to check isRunning rather than keeping its own record
of whether the animation is running.

- Scale to an arbitrary size, using the decoding library if it supports
it, and Skia otherwise
- Crop to a subset
- Post-processing with an SkPicture, to facilitate circle masks etc
- isRunning, to implement Animatable2 interface in Java

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.
