Trigger haptic feedback when a long-press gesture fires a right-click
(context menu) in the Android editor. Uses Android's native
`HapticFeedbackConstants.LONG_PRESS` on the render view surface.
An editor setting `interface/touchscreen/haptic_on_long_press` is added
under the existing touchscreen section to allow users to disable this
behavior. The setting defaults to enabled on native touchscreen devices.
