347eaa32bf relay: Lower DNS Exit-side timeout 
Introduces two new consensus parameter:

  exit_dns_timeout: Number of seconds before libevent should consider
  the DNS request a timeout.

  exit_dns_num_attempts: Number of attempts that libeven should retry a
  previously failing query before calling it a timeout.

Closes #40312

254b23ab9d hs: Schedule mainloop event on dirinfo change 
Due to a possible Guard subsystem recursion, when the HS client gets
notified that the directory information has changed, it must run it in a
seperate mainloop event to avoid such issue.

See the ticket for more information on the recursion. This also fixes a
fatal assert.

Fixes #40579

069b278601 hs: Don't BUG() when setting up RP congestion control 
It is possible to not have the descriptor anymore by the time the
rendezvous circuit opens. Don't BUG() on that.

Instead, when sending the INTRODUCE1 cell, make sure the descriptor we
have (or have just fetched) matches what we setup in the rendezvous
circuit.

If not, the circuit is closed and another one is opened for a retry.

(the idea is that ReleaseNotes is for learning what you get when you
move from one stable to another, whereas ChangeLog is for learning what
changed in each released version of tor.)
