network: add WifiDeviceMode, update NM wireless logic

- Add WifiDeviceMode and WifiDevice.mode
- Add module.md
- Reimplement NMWirelessNetwork
- Fix mode checking for NMWirelessDevice
onConnectionLoaded/onAccessPointLoaded
- Move security type to bindings in NMAccessPoint and
NMConnectionSettings

+For now, the only backend available is the NetworkManager DBus interface.
+Both DBus and NetworkManager must be running to use it.
