* Source/WebKit/UIProcess/ios/WKContentViewInteraction.mm:
(-[WKContentView allowsTouchPanningAtPoint:]):
Expose to clients whether the page allows touch-based panning at a given point 
via the touch-action CSS.
This could be used to, for example, control whether client-owned pan gestures 
used for things
other than scrolling should be disabled in order to defer to the content.

* Tools/TestWebKitAPI/Tests/ios/ScrollViewScrollabilityTests.mm:
(TestWebKitAPI::TEST(ScrollViewScrollabilityTests, TouchActionPanAPI)):
Add a test.
