This reverts commit 306a09a3.

This updates to use the new HttpClientResponse.compressionState
API that was recently added in the SDK.

https://github.com/flutter/flutter/issues/32374

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.

https://github.com/flutter/flutter/issues/32374

This will allow us to plumb the chunks in a chunked response
up to the higher levels of the framework to notify interested
parties of network loading progress.
