shared/att: Support multiple disconnect handlers.

This patch adds support for registering multiple disconnect handlers with an
instance of struct bt_att. Unregistering is achieved via a new function AND
through bt_att_unregister_all and all disconnect callbacks get automatically
unregistered after a single disconnect event.
