knownnetworks: add option to force a default ECC group 

This adds the option [Settings].UseDefaultEccGroup which allows a
network profile to specify the behavior when using an ECC-based
protocol. If unset (default) IWD will learn the behavior of the
network for the lifetime of its process.

Many APs do not support group 20 which IWD tries first by default.
This leads to an initial failure followed by a retry using group 19.
This option will allow the user to configure IWD to use group 19
first or learn the network capabilities, if the authentication fails
with group 20 IWD will always use group 19 for the process lifetime.
