Add protected overload of initializeFromPeer() for backend devices

Subclasses should call this from their overloads to set up the base
device properties.

Since we do not yet know if all AxisSettings objects will exist by
this time, just store the id's of them and we will add a job to
extract the settings in the next frame once we know they will all have
backend objects.
