Description
Currently, there is effectively no limit to the size of a /_matrix/federation/v1/send/{txnId} request, because some EDUs (eg presence, receipts) can reasonably contain an unlimited quantity of data. I think we should specify some limits to the amount of data such EDUs can contain.

Research direction
Start with the /_matrix/federation/v1/send/{txnId} endpoint and review how EDUs such as presence and receipts are described in the Matrix specification. Define and document limits for the amount of data those EDUs can contain, with the specification clearly stating the resulting maximum size.
