wifi-display: add certification options

When certification mode is enabled:

- Pass wfd session info to wifi display settings

- Allow sink to connect to source

- Add interface in display manager for pausing/resuming session

- Add interface in WifiP2pManager for setting lc, oc and starting
  autonomous GO

Note that we're compliant regardless of certification mode, but
some confusing options (eg. allowing incoming connection from
sink) we want to hide when not being tested.
