Implement AnimatedImageDrawable#setBounds

Bug: 160617841
Test: If6edcada514977c2f08c29927380d35000173dc5

AnimatedImageDrawable.java:
- Override onBoundsChange. Silently do nothing if mNativePtr is 0. This
matches setRepeatCount, setAutoMirrored, and onLayoutDirectionChanged.
While some other methods throw an IllegalStateException, doing nothing
is safer for backwards compatibility.

AnimatedImageDrawable.h:
- Add Properties.mBounds. Putting it here provides a safe way for the UI
thread to change it, like it does for other properties (alpha, color
filter).
- Remove redundant "virtual" modifiers on "override" methods.

hwui/AnimatedImageDrawable.cpp:
- Initialize mStagingProperties.mBounds to use the intrinsic bounds. The
official documentation requires a client of Drawable to call setBounds,
but AnimatedImageDrawable as introduced in P started with the intrinsic
bounds. This ensures we maintain that behavior without special casing a
client that never calls the method.
- Handle the bounds, using a scale and translate
- Update the SkAutoCanvasRestores to save, removing the need to manually
determine whether it's necessary to call save().
- Update onGetBounds to return SkRectMakeLargest. This matches
RenderNodeDrawable and ReorderBarrierDrawables. Since the Drawable may
be updated by a call to setBounds to draw anywhere, this ensures the
bounds always contains the drawing.

jni/AnimatedImageDrawable.cpp:
- Plumb the new bounds to the native object.
