tests: Modify autogo_scan to support P2P Device interface

tests: Modify autogo_scan to support P2P Device interface

Support configurations that use a dedicated P2P Device interface by
sending the P2P_CONNECT command on the global control interface.

In addition, when a dedicated P2P Device interface is used, there is no
need to manually respond to the Provision Discovery Request since the
request is processed by the P2P Device interface and this interface was
not set for external RX management frames handling.
