[iOS] Adopt `-[UIScrollView
setTransfers(Horizontal|Vertical)ScrollingToParent:]`
https://bugs.webkit.org/show_bug.cgi?id=263755
rdar://114330057
Reviewed by Richard Robinson.
Adopt equivalent replacement APIs, corresponding to these two `UIScrollView`
SPI methods:
• `-_setAllowsParentToBeginHorizontally:` ->
`-setTransfersHorizontalScrollingToParent`
• `-_setAllowsParentToBeginVertically:` ->
`-setTransfersVerticalScrollingToParent`
To make this work while maintaining compatibility with iOS 17 and prior, we add
a new compile-time
flag along with a runtime selector check, and only use this new API when both
checks pass.
* Source/WTF/wtf/PlatformHave.h:
Remove a compile-time flag that's no longer needed.
*
Source/WebKit/UIProcess/RemoteLayerTree/ios/ScrollingTreeScrollingNodeDelegateIOS.mm:
(WebKit::ScrollingTreeScrollingNodeDelegateIOS::updateScrollViewForOverscrollBehavior):
* Source/WebKit/UIProcess/ios/UIKitUtilities.h:
* Source/WebKit/UIProcess/ios/UIKitUtilities.mm:
(-[UIScrollView _wk_setTransfersHorizontalScrollingToParent:]):
(-[UIScrollView _wk_setTransfersVerticalScrollingToParent:]):
Add new helper category methods on `UIScrollView` to abstract away the fallback
logic described
above.
