MSC2938: Report content to moderators

[Yoric]

As a followup to https://github.com/vector-im/element-meta/issues/1848, this proposal introduces a mechanism to report content to room moderators instead of reporting it to homeserver administrators.

I have added a first draft of how to make this work with federation.

Leaving my thoughts here like i did in the synapse-dev room: I think the best course of action would be to make this an _unstable endpoint (if anything, for now), never stabilising it to a normal endpoint, and fixing the eventual problem with a homeserver-to-homeserver room, which'd require a seperate MSC.

(This room would establish a DM with another homeserver "server" user (e.g. @server:<serverpart> or @:<serverpart>), and then send any server-to-server informational data over that room, over federation)

I have no problem with using the _unstable, especially for a prototype.
