rpc(getpeerinfo): Add inbound peers to method response

[oxarbitrage]

Motivation

We want to return outbound and inbound peer addresses in the getpeerinfo response. We currently return only outbound connections as these are the only ones we have access to by the address book.

Solution

• Add an AddressBookType to the AddressBook structure so we can have 2 books, one for each type without interfering one with the other.
• Change the returned peers of the rpc to be only the ones that are likely to be connected to us.

There are several ways to do this, i decided for upgrading the current address book structure with the addition of the type because there are multiple fields in the zcashd response that are available in the address book structure we might need to add in the future.

Tests

A basic unit tests was extended to check the inbound address book case. Existing tests were modified to have the outbound type so everything keeps passing. More tests can be created.

This looks like it should work, but it seems unnecessary to add another address book.

I made an alternative change in a9014f0 of #9201 if that looks acceptable.

Related: @mpguerra It would be nice to eventually refactor the address book into a service, it may be easier to do that ahead of adding fields to the getpeerinfo response.
