Add support for ImageStreamListener.onChunk() (#33092)
This is another step towards supporting image loading
progress notification at the widgets layer.

This adds an `ImageChunkEvent` class along with associated
`ImageChunkListener` callback signature and an `onChunk`
property to `ImageStreamListener`. The events serve to
notify registered listeners when byte chunks are received
while loading an image.
