Our "close all exchanges except this special one for this fabric" API messes up exchange refcounting, leading to use-after-free. The fix is to reuse, as much as possible, the normal "session is going away" flow to notify exchanges, and other session consumers, that the sessions are in fact going away. Fixes #19747
We need to allow messages on inactive sessions to reach the exchange manager, because such sessions need to be able to deliver an MRP ack to an exchange waiting for one. We also don't want to crash on an attempt to transition from Inactive to Defunct state; the transition should just be ignored. This way if we start trying to transitionin to Defunct on MRP delivery failures we will not start crashing if such a failure happens on an Inactive session.
