The host-based adv auto-resume function has both a problematic implementation and disagreement in the community around how it should behave. See the issue linked resolved below for details. This patch makes the deprecation visible to the user. The user will be better served by a auto-resume tailored their applications use case, based on more primitive host API like `conn_cb.recycled`, which has obvious behavior that is unlikely to change.
