allow external USB host management
- Setting config_UsbDeviceConnectionHandling_component leads into
launching specified Activity whenever USB device is connected.
- This allows external Activity to manage USB device based on
its own setup and settings.
- Device access can be passed to other app with permission update
by UsbManager.grantPermission.
- added UsbDeviceConnection.resetDevice() to reset USB device connected.
This is necessary to get device out from AOAP.
- Test requires installing UsbHostExternalManagmentTestApp and
AoapTestHost to USB host, and AoapTestDevice to USB Device.
