Merge bitcoin/bitcoin#29279: test: p2p: check disconnect due to lack of desirable service flags

Browse Source 
2f23987849 test: p2p: check limited peers desirability (depending on best block depth) (Sebastian Falbesoner)
c4a67d396d test: p2p: check disconnect due to lack of desirable service flags (Sebastian Falbesoner)
405ac819af test: p2p: support disconnect waiting for `add_outbound_p2p_connection` (Sebastian Falbesoner)

Pull request description:

  This PR adds missing test coverage for disconnecting peers which don't offer the desirable service flags in their VERSION message:
  5f3a0574c4/src/net_processing.cpp (L3384-L3389)
  This check is relevant for the connection types "outbound-full-relay", "block-relay-only" and "addr-fetch" (see `CNode::ExpectServicesFromConn(...)`). Feeler connections always disconnect, which is also tested here.

  In lack of finding a proper file where this test would fit in, I created a new one. Happy to take suggestions there.
