Use TEXT_HANDLE_MOVE in TextView behind the flag

This CL enables TextView to trigger
HapticFeedbackConstants.TEXT_HANDLE_MOVE on devices that explicitly
enable this feature with resource overlay.  This CL should have no
behavior change and no performance impact by default.

Since the use case of HapticFeedbackConstants.TEXT_HANDLE_MOVE is
when the user is manually moving the text insertion/selection handle
on the touch screen, it is intentional that text handle move
triggered by hardware keyboard, mouse, TextView APIs, IME APIs, and
any other internal API calls do not trigger the haptic feedback
even if the feature is enabled with resource overlay.

Bug: 62454887
Test: Manually done as follows.
  * Not triggered on cursor move by mouse
  * Not triggered on cursor move by hardware keyboard
  * Not triggered on cursor move by IME
  * Triggered on cursor move by touch screen
