refactor(iroh-net)!: Rename Endpoint::local_addr to bound_sockets (n0…

…-computer#2366)

## Description

This renames Endpoint::local_addr to Endpoint::bound_sockets.  We have
a lot of different meanings for "addr" and also don't really have a
notion of "local_" prefix, since the endpoint is not 1:1 connected
with a peer.  The "local_" naming comes from connected sockets which
have local_addr and peer_addr, which is not applicable for the
Endpoint.

## Breaking Changes

- Endpoint::local_addr -> Endpoint::bound_sockets

## Notes & open questions

<!-- Any notes, remarks or open questions you have to make about the PR.

## Change checklist

- [x] Self-review.
- [x] Documentation updates if relevant.
- ~~[ ] Tests if relevant.~~
- [x] All breaking changes documented.
