[chromium] correctly handle move drag operations

This is to work around the fact that the "move" maps to DragOperationGeneric (see https://bugs.webkit.org/show_bug.cgi?id=33697).

This is consistent with what happens in WebKit/WebKit/win/.

I think the creation of DragData could also be shared in this function.
    DragData dragData(
        m_currentDragData.get(),
        clientPoint,
        screenPoint,
        static_cast<DragOperation>(operationsAllowed));

Probably it might be better to call it as dragTargetDragEnterOrOver.
In addition, since WebKit does not have line length, we do not need to split the long comment into 3 tidy lines.

Done.

I renamed the function to dragTargetDragEnterOrOver, but kept the comment as 3 lines because that matches the style in the rest of the file.

Since https://bugs.webkit.org/show_bug.cgi?id=33697 got r+, I'm going to rev this patch to no longer need the GENERIC -> MOVE conversions.

"bool isEntering" should be an enum, so it is clearer at the calling site what the function is being passed (instead of "true/false" be passed into the function).

Single space after . in comments (in WK land). Sorry, I should have caught this last time.

Fixed throughout the file.  If this is really something that's important, it should be in the style checker.
