v1.17: quic: delay calling set_max_concurrent_uni_streams/set_receive_window (backport of #904)

[mergify]

Delay calling connection.set_max_concurrent_uni_streams() and connection.set_receive_window() to when we know we've accepted the connection. Avoids a short window where the peer could start transmitting even if we're going to drop the connection, and avoids taking the connection mutex and waking a task.

This pr was created before the bp enforcing rules kicked in so the groups were not added properly, I'm approving since we've got the other 2 approvals
