This reverts commit 4fdf9f9ce5.
Reason for revert: Google3 and ASAN failures caused by the prior

Bug: skia:10914
Bug: b/163595585
In a WebP image, it is possible to combine animation with an EXIF
orientation. While SkAndroidCodec attempts to handle orientation itself
by decoding into temporary memory and then drawing through a matrix,
this doesn't work directly when compositing a P-frame into a prior
frame. SkAnimatedImage already uses an SkMatrix to handle cropping and
scaling, so update that matrix to include the orientation.
Make SkAnimatedImage a friend of SkAndroidCodec. This allows the former
to have the same ExifOrientationBehavior specified by the latter, and to
recreate the latter so it does not try to handle the orientation itself.
Clip SkAnimatedImage to its bounds. Android's AnimatedImageDrawable
performs its own clip, but this makes a crop rect work for other
clients.
Update getCurrentFrame to take cropping, scaling, and orientation into
account. This method is used by CanvasKit, which does not use cropping
or scaling, but will now properly orient an animation with an EXIF
orientation.
Add a GM that exercises the various combinations of ways SkAnimatedImage
can be used:
- via newPictureSnapshot (as in Android) versus getCurrentFrame
- scaling down to a dimension that can be output from the
SkAndroidCodec, versus up, which SkAnimatedImage scales
- with a crop rect
- with a post processor

The only caller is CanvasKit, and SkAnimatedImage already has getBounds
(from SkDrawable) which does the same thing, except it returns
SkScalars. It also takes scaling and cropping into account, which
CanvasKit does not use, and in a future commit, it will consider
orientation. Switch CanvasKit to use getBounds.

This version was used before we added the version with an SkImageInfo

Mechanically updated via Xcode "Replace Regular Expression":

using INHERITED = $1;
The ClangTidy approach generated an even larger CL which would have
required a significant amount of hand-tweaking to be usable.

Flutter on the web wants to be able to extract arbitrary frames from
an animated image and pass those into functions like:
drawAtlas, drawImage, drawImageRect
This should allow that to happen w/o having to add lots of variants like
drawAnimatedImage. If this sticks, is drawAnimatedImage still useful?
(maybe it saves a copy?)

Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

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.

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.

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.
