Refactor the URLResponseInfo to use new design

This puts all of the URLResponseInfo attributes in a struct so it can be sent over IPC in one message rather than requiring one sync IPC per attribute access.

This includes a new example of streaming to a file that I used to do some manual tests of this change.

I added and improved some documentation that I noticed when trying to write the example.
