The shared memory handle reporting has been generalized to be an external handle reporting. This is used for both shared memory, and for volatile memory (on Android.) This will allow us to have a better sense of just how many handles are being used by images on Android. Additionally we were not properly reporting forced heap allocated memory, if we were putting animated frames on the heap. This is because we used SourceSurfaceAlignedRawData without implementing AddSizeOfExcludingThis.
