Turn AVM FRITZ!Box Tools call deflection switches into coordinator entities

[mib1185]

Proposed change

This reduces the API calls, prior each existing call deflection caused one API call to fetch all deflections and filter to the current one, now all call deflections are get by the coordinator once and each call deflection entity use the data from coordinator. If there are about 20 existing call deflections, only 1 call is made as opposed to 20 before.

This is also the pre-work for migrating the other switch (port forwarding, wifi and profile) entities.
