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.

The current API was broken in that you registered multiple
callbacks at once, but when you removed listeners, only the
primary listener was used to determine what was removed.
This led to unintuitive cases where the caller could get
unexpected behavior.

This updates the API to add and remove listeners using
a newly introduced [ImageStreamListener] object, a value
object that has references to the individual callbacks
that may fire.

This will allow us to plumb the chunks in a chunked response

Currently, the fact that NetworkImage uses a static HttpClient
makes it impossible to properly test, as a mock in one test will
be reused in another test. This change fixes that.
