* Source/WebCore/platform/ios/LocalCurrentTraitCollection.h:
* Source/WebCore/platform/ios/LocalCurrentTraitCollection.mm:
(WebCore::LocalCurrentTraitCollection::LocalCurrentTraitCollection):
Expose a version of LocalCurrentTraitCollection that takes a trait collection
and makes it current, while also applying `adjustedTraitCollection`'s adjustments.

* Source/WebKit/UIProcess/ios/DragDropInteractionState.mm:
(WebKit::DragDropInteractionState::updatePreviewsForActiveDragSources):
Adopt LocalCurrentTraitCollection here in order to make `adjustedTraitCollection`'s
adjustments take effect for the UIURLDragPreviewView's background color.
