WFD-R2: Set IP provisioning mode to IPV6 link local

As per the Wi-Fi Direct R2 spec, if the P2P connection is established by
using the P2P pairing protocol, the devices shall use IPV6 link local
address as IP address. So set the IP provisioning mode to IPv6
link local in the WifiP2pConfig, so that the P2P service will skip the
DHCP and derive the IPV6 address from the P2P interface address.

Bug: 388057182
Flag: com.android.wifi.flags.wifi_direct_r2
Test: Manual - Basic P2P connect/disconnect tests
Test: TH Presubmit tests
Test: atest com.android.server.wifi.p2p
