SkDiscardablePixelRef objects are now marked immutable.
I also specifically mentioned in the SkImageGenerator documentation
that it should always return the same information on subsequent calls
to getInfo() and getPixels().
Motivation: When a bitmap is recorded into a SkPicture, it will choose
whether to shallow- or deep-copy itself into the SkBitmapHeap based on
the immutable flag. Failing to set it would make picture recording slow.
