Initial implementation of MSC3981: recursive relations API (#15315)
Adds an optional keyword argument to the /relations API which
will recurse a limited number of event relationships.

This will cause the API to return not just the events related to the
parent event, but also events related to those related to the parent
event, etc.

This is disabled by default behind an experimental configuration
flag and is currently implemented using prefixed parameters.
