ryu: update PD swaps configuration

- allow power swap only when we are dual-role toggling (ie in S0).
- enable the VCONN swap feature to support more type-C dongles.
  and allow it using the same rule as power swap.
- become a power sink when we are connected to an externally powered
  DRP.
- by default, try to be a data UFP for USB.
  so Dual Role Device such as laptops can get our data.
- add a message to inform the AP that our USB role has changed
  (but the host events are fully wired yet on Ryu)
