refactor: improve criteria for choosing peers to save to resume (#6922)
* fix: only consider peers with listening ports interesting

It's a waste of space to store peers we cannot connect to (because we don't know what their listening port is).

* fix: don't consider peer as interesting just because we are currently connected to it

For example, it's possible for a peer to be "in-use" and "banned" at the same time, albeit just for a very short while.

* code review: assert that peer port is not empty

fix: various pex flag bugs and cleanup (#6917)
* fix: allow connection between seeds when pex is enabled

* chore: add comment to explain `tr_peerMsgs::on_torrent_got_metainfo()`

* refactor: remove `tr_swarm::mark_peer_as_seed()`

* fix: update seed flag in response to BT msgs

Regression from 81a42c6bb6

* chore: remove redundant code to update peer seed flag

* refactor: inc failure count if there were no piece data exchanged

* fix: save information from ltep handshake

* refactor: rename `tr_peerIo::is_seed_` to disambiguate

* fix: add instead of set pex flags when adding non-pex and non-resume peers

* fix: don't mark peer as connectable on getting ltep port msg

By BEP-11's definition, this flag is only set for peers whom we successfully initiated an outgoing connection with.

* refactor: set holepunch flag when we get it from ltep handshake

* fix: only accept positive `reqq` in ltep handshake

* refactor: handle encryption preference in `tr_peer_info`

* refactor: prefer own value for utp support

* refactor: make `tr_peer_info::from_first_` const

* refactor: handle holepunch support in `tr_peer_info`

* fix: parse metadata size only if we have a valid extention id for metadata xfer

* refactor: remove `tr_peer_info::add_pex_flags()` as it's no longer needed

* fix: correctly handle holepunch support when there is no `m` key in ltep handshake

* fix: distinguish between upload only and seed

Say we just connected to a partial seed, the peer sends an ltep handshake that has the `upload_only` key, then a BT `Bitfield` message:

Without this change, the pex seed flag would be set when parsing the ltep handshake, then immediately unset when parsing the `Bitfield` message.

We don't want that.

* fix: don't update `tr_peer_info::is_seed_` when merging peer info objects

* perf: priority in peer candidate score need 2 bits only

* fix: prefer to connect to downloading peers

Regression from c867f00153

* chore: add TODO for C++20 opportunity

* refactor: don't filter out peers without `ADDED_F_CONNECTABLE`

revert change from a2849219f7

* refactor: move peer state updates out of peermgr code
