P2P: Add automatic GO Negotiation vs. join-a-group selection

p2p_connect command can now be used with an optional "auto" parameter
to request wpa_supplicant to determine automatically whether to use
join-a-group operation (if the peer is operating as a GO) or group
formation. This makes it easier for external programs to handle
connection type selection by offloading this to wpa_supplicant. The
previously used p2p_connect join commands can be replaced with
p2p_connect auto to use this new mechanism.
