USB: Add API and dialog for apps to request permissions for USB devices and accessories
New APIs:
UsbManager.hasPermission returns true if the caller has permission
for the given device or accessory
UsbManager.requestPermission poses a dialog to allow the user to give the caller
permission for the device or accessory.
Result is returned via a PendingIntent.
No dialog is displayed if the caller already has permission.
Also moved UsbResolverActivity to SystemUI package
BUG: 4069037
