Block haptic text handle at the policy layer.

This means that we globally enforce the haptic text handle events, even
if they're coming from something other than TextView. Prior to this,
things like WebView would cause haptic feedback on text handle movement
if the tick effect was implemented even if the feedback was disabled by
the configuration.

We've left the code in Editor that blocks text handle haptic feedback
just to avoid paying the cost of an IPC call whenever the handle moves
on devices where it's disabled.
