Nika Layzell 95a883d65d Bug 1754004 - Part 3: Move RemoteLazyInputStream to its own toplevel protocol, r=asuth,necko-reviewers,dragana
This is a complete rewrite of RemoteLazyInputStream to run off of its own
toplevel protocol, rather than being managed by other protocols like
PBackground or PContent. This should improve performance thanks to no longer
needing to operate on a main or worker thread, and due to no longer needing the
migration step for the stream actor.

This also acts as a step towards no longer requiring a manager actor to
serialize input streams, as the type is now actor-agnostic, and should support
being sent over IPC between any pair of processes.
