Reviewed by Richard Robinson.

The CSS `touch-action` rule that double-tap-to-zoom-like gestures are
disabled by both `none` and `manipulation` can be shared by multiple
readers.

In this patch, we make it a single inline predicate, and we adopt it in
WKTouchActionGestureRecognizer. More callers will follow.

* Source/WebCore/platform/TouchAction.h:
(WebCore::touchActionAllowsDoubleTapToZoom):
* Source/WebKit/UIProcess/ios/WKTouchActionGestureRecognizer.mm:
(-[WKTouchActionGestureRecognizer canPreventGestureRecognizer:]):
