bluetooth: host: remove useless internal flag BT_ADV_PERSIST

Automatic advertiser resumption is publicly deprecated since
Zephyr 4.0 [1].

Options and parameters for this behavior have been removed,
and the internal bit flag BT_ADV_PERSIST is now always false.

The behavior it used to configure (to keep advertising after a
connection has been established as long as there are connections
available) has also been removed.
