Split out from #27885

@javiercn Can you fill in details? No need for a full-scale design proposal unless you're really committed to this.

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

Please see #36991 (comment). As part of this task we'll need to ensure we're preserving the original blob (via a JSObjectReference) when round-tripping the IBrowserFile.

@SteveSandersonMS I'm going to close this issue and use #25274 to track it.

I think a big chunk of the work is done here (the support for streams we added in 6.0) and the remaining work would be handled as part of the issue mentioned above.
