Add static meta-data for x-ardour/region.pbdid DnD

Browse source 
During drag-motion callbacks the data to be dragged is n/a.
However we like to discriminate if drop is possible.

When dragging regions, the data-type of the region to be dragged
is unknown, so different `x-ardour/region` targets are not an
option, either.

Until a better option is presented, a static global is used
to set the data-type for region.pbdid drags.
