Introduce HapticFeedbackConstants.TEXT_HANDLE_MOVE

This CL	introduces a new haptic feedback type for the scenario where
the user is manually moving the text insertion/selection handle on the
touch devices such as touch screen.

Having a dedicated constant is necessary for device-wide consistency and
flexibility to fine tune the feedback in future.
