- This patch separates RFPTarget::PointerEvents into PointerEvents and PointerId. - PointerId protection is disabled for Android. - WidgetEvents emit non-primary mouse events on Android because any touch other than 1nd touch is considered non-primary - Sets maximum touch points to 5 on Android Differential Revision: https://phabricator.services.mozilla.com/D221241
