Framework Introduce CallbackWrapper

there is a bunch of profiles that register callback to the bluetooth
service, this logic is repeated again and again.

By having a common wrapper we can:
* Finnaly have some tests on the registration logic (none before)
* Make sure all the profile are registering callback the same ways
* remove duplicates code

This initial CL only implement it for HAP, other profiles will be done
in follow up
