[Site Isolation][macOS] Transform mouse coordinates for drag events when
forwarding to an iframe process
https://bugs.webkit.org/show_bug.cgi?id=264611
rdar://118244400
Reviewed by Charlie Wolfe.
Instead of directly passing dragData.clientPosition() to the drag controller we
first transform it to map to the remote frame's coordinate space, similar to
how this is already handled for mouse and touch events. This logic is
implemented for both DragController::dragEnteredOrUpdated() and
EventHandler::dragSourceEndedAt() along with accompanying APITests which
confirm coordinate transformation as LayoutTests do not currently support
testing drag and drop in WK2.
