Stop applying edits to event contents (MSC3925). (#15193)

Browse source 
Enables MSC3925 support by default, which:

* Includes the full edit event in the bundled aggregations of an
  edited event.
* Stops modifying the original event's content to return the new
  content from the edit event.

This is a backwards-incompatible change that is considered to be
"correct" by the spec.
