[PATCH v2 3/5] shell32/tests: add mock IDataObject instances

[Tarcísio Ladeia de Oliveira]

From: Tarcísio Ladeia de Oliveira

The drag and drop helpers require the use of IDataObject with GetData()
and SetData() implemented, being able to store "arbitrary private
formats". Currently implements the interface with those functions being
either empty or not implemented.
