shared: add NMU_IFACE_ANY for nm_utils_ifname_valid()

nm_utils_ifname_valid() is to validate "connection.interface-name"
property. But the exact validation depends on the connection type.

Add "NMU_IFACE_ANY" to validate the name to check whether it would be
valid for any connection type.

This is for completeness and for places where the caller might not know
the connection type.
