P2P NFC: Static handover with NFC Tag on client

P2P NFC: Static handover with NFC Tag on client

This adds a new P2P Invitation mechanism to invite a P2P Device with an
NFC Tag to an already operating group when the GO with NFC Device reads
the NFC Tag. The P2P Device with the NFC Tag will then accept invitation
and connect to the group automatically using its OOB Device Password.
