<pre>[iOS] Teach postprocess-headers.sh to remove code guarded by ENABLE_IOS_GESTURE_EVENTS
and ENABLE_TOUCH_EVENTS if applicable
https://bugs.webkit.org/show_bug.cgi?id=135993
Reviewed by Andy Estes.
Add support infrastructure to remove code from public and private API headers that is
guarded by macro define ENABLE_{IOS_GESTURE, TOUCH}_EVENTS when these features are disabled.
We aren't using this functionality yet, but we will soon.
