[iOS DnD] For cross-app drags, 'drop' event handlers are never invoked if dataTransfer.dropEffect is not set while dragging
https://bugs.webkit.org/show_bug.cgi?id=174219
<rdar://problem/32083177>
Reviewed by Ryosuke Niwa.
Source/WebCore:
Currently, in DragController.cpp, defaultOperationForDrag maps a drag source operation mask of
DragOperationGeneric to DragOperationMove across all platforms. However, on iOS, where cross-app drag moves do
not trigger a drop, this means drop handlers won't fire unless the dropEffect is explicitly set to copy.
To fix this, we introduce DragController::platformGenericDragOperation(), which returns DragOperationCopy on iOS
and DragOperationMove (the existing behavior) elsewhere. defaultOperationForDrag then maps a drag source
operation mask of DragOperationGeneric to platformGenericDragOperation().
Tests: DataInteractionTests.ExternalSourceHTMLToUploadArea
DataInteractionTests.ExternalSourceImageAndHTMLToUploadArea
DataInteractionTests.ExternalSourceMoveOperationNotAllowed

Tweak some testing SPI to return a drop operation flag instead of whether or not the drop operation was not
UIDropOperationCancel.

Tools:
Add plumbing and support to mock the value of -allowsMoveOperation on the simulated UIDragDropSession objects.
Setting the DataInteractionSimulator's shouldAllowMoveOperation property to NO simulates a drag operation coming
in from another app out-of-process, for which move operations won't cause a drop to be performed in the first
place.
Also tweaks 2 existing unit tests regarding file uploads via _javascript_ to simulate items coming in from a
different application, and adds a new test to check that if a drop area specifically requests a MOVE operation,
no action is taken when dropping.
