…ardown.
server_fuzz_test indicated the below crash, where the DispatcherImpl teardown
releases some upstream client SSL related objects that then needs
SecretManagerImpl to unregister. Previously, this was already destructed by
time we were in ~DispatcherImpl(), this PR reorders.

Risk Level: Low
Testing: Corpus entry added. It's pretty hard to build regressions for this
kind of destruction ordering, so relying on server_fuzz_test + corpus.

This test wants to send a stream reset when the remote has the response EOD buffered. However, nothing prevented the request being fully completed before the reset was sent. If that happened, a UAF would happen as observed by ASAN:

To fix this, use flow control to prevent the fake upstream from sending all its data before a reset is sent.

This test sends a large number of metadata frames in order to trigger a disconnect. However, it was possible for the disconnect to happen and the connection to be torn down before all the metadata frames had been sent. If that happened, ASAN detected a UAF:
