connman: build with --enable-iwd, add build option "nftables", split openconnect plugin, remove runtime dependency on wpa_supplicant
1. Build with --enable-iwd

    iwd is a better alternative to wpa_supplicant.

1. Add build option "nftables"

    Allow to build with support for nftables instead of iptables.
    
    From ./configure --help:
    
        --with-firewall=TYPE    specify which firewall type is used iptables or
                                nftables [default=iptables]

1. Split openconnect plugin into subpackage
    
    OpenConnect VPN is not widely used and it adds many dependencies to the connman package. On my system, removing openconnect orphaned the following packages: openconnect trousers vpnc-scripts libpcsclite mit-krb5-libs with total size over 5 MiB.

1. Remove runtime dependency on wpa_supplicant
    
    ConnMan can be used with iwd or even without any WiFi program, because it can be used for Ethernet devices.

1. Split openvpn and wireguard to subpackages
    
    The main motivation to split openvpn into a subpackage is to correctly declare its dependency on "openvpn" package. Wireguard doesn't seem to depend on any other package, that's just for consistency with other VPN plugins.
