Revert "Bluetooth: Host: Disable host-based RPA resolution when !BT_PRIVACY"

Browse source 
This reverts commit 5824ac90ecd8dd06d9ea117d345dbc6b069e5840.

The resulting revert takes into account changes to the predicate that
guards the use of `resp_addr`.

In the resulting revert, the predicate guarding the use of `resp_addr`
is differs from the naive revert because the intention of that predicate
is to know when `conn.c:bt_conn_le_create` decided to use the Host
resolver. And, the logic in `conn.c:bt_conn_le_create` has changed. The
changes to the logic in `conn.c` are in the following commits:

Enable Privacy Feature support. This makes it possible to generate and use
Resolvable Private Addresses (RPAs).
Disabling this will remove the capability to resolve private addresses.
