Add USB port manager. Add some new internal APIs to enumerate USB Type C ports, query their status, determine whether they support changing power or data roles, and doing so. The API also adds a new ACTION_USB_PORT_CHANGED broadcast for port state changes. The implementation includes a mechanism for simulating the behavior of the USB stack. See 'adb shell dumpsys usb -h' for details. Note that the underlying kernel driver interface is still subject to change but its behavior has been encapsulated as much as possible.
