cellular: add a property to enable/disable passing the attach APN

The use_attach_apn_ cellular property exported as
'Cellular.UseAttachAPN' decides whether shill should explicitly set in
the modem the desired 'attach APN' before registering to the network by
using the data from the mobile operator database.

When this property is false, the host side sends no configuration and
the modem will use its own internal database or get the value from the
network.

It is currently disabled by default.
This property can set/read over D-Bus, this will be used to implement
the Chrome flags enabling it.
