The behavior was unintentionally changed in 2858c3b287. This patch brings back
the old behavior when dragging objects/collections from the asset browser into
the 3d view, while still keeping the loose-data-instantiation separate from the
core import code.
The `view3d_ob_drop_copy_external_asset` and `view3d_collection_drop_copy_external_asset`
functions are turned to their old state before the refactor.
