Generate enum/getters/setters for -webkit-app-region.
Currently, the -webkit-app-region (named DraggableRegionMode internally)
property is a 'storage_only' field, so it has no generated public
getters/setters.
This patch changes it to a 'keyword' field so that its getters/setters
can be generated as well. We also generate the EDraggableRegionMode enum.
Although there are generated CSSValueID <-> EDraggableRegionMode mappings,
they are not used because the handwritten code don't have them.
