Move touch slop suppression from LegacyTouchEventQueue to TouchEventManager

*** This is a selected minimal part of the cherry-picked CL ***

We do not want to suppress pointer events, but the current code suppresses touch events from browser side, so the pointer events are also suppressed. We move the slop region suppression code to TouchEventManager, so all the pointer moves will be dispatched.

Please remove the rest of the function body. Otherwise some compilers could fail
