Implement MSC3925: changes to bundling of edits (#14811) 
Two parts to this:

 * Bundle the whole of the replacement with any edited events. This is backwards-compatible so I haven't put it behind a flag.
 * Optionally, inhibit server-side replacement of edited events. This has scope to break things, so it is currently disabled by default.

Test the behaviour of relations when the parent or child event is redacted.
The behaviour of each relation type is subtly different which causes the tests
to be a bit repetitive, they follow a naming scheme of:

The first bit of "relation" means that the event with the relation defined
on it (the child event) is to be redacted. A "parent" means that the target
of the relation (the parent event) is to be redacted.
The relation_type describes which type of relation is under test (i.e. it is
related to the value of rel_type in the event content).
