[netdata] move service ALOC management from MLE module (#11815)

This change moves the service ALOC management logic from the `Mle`
module to `NetworkData::Service::Manager`.

This change simplifies the code by consolidating responsibilities.
Since the `NetworkData::Service` module manages service entries in
the Network Data, it is the logical owner for managing the associated
service ALOCs.
