Expose whether device supports 5GSA or only 5GNSA
ModemManager should expose whether a 5G capable device supports only NSA or also SA.
The current capabilities mask provides a single "5GNR" value that doesn't specify the type of 5G supported. E.g. two possible options:
- Maybe we should provide a bitmask that specifies only 3 values:
UNKNOWN (0), 5G_SA (1<<0), 5G_NSA (1<<1)
. - Or maybe we should provide a more detailed bitmask that specifies also the type of NSA if available, e.g.:
UNKNOWN (0), 5G_SA (1<<0), 5G_NSA_ENDC (1<<1), 5G_NSA_NEDC (1<<2), ....
Ideally, we would look at AT/QMI/MBIM references and see which of the two possible options fit better to cover all protocols.
