Batch deletion of IDs could lead to deleting ObData ones while keeping the related ShapeKeys. Orphaned shape keys are not allowed anymore in Blender, they are checked against in both file write and read code. This would lead to assert (and crash) e.g. in the liboverride code. This commit forcefully add shapekeys of deleted meshes, curves etc., when calling e.g. `BKE_id_multi_tagged_delete`. Note that deleting the shapekey when deleting the obdata ID was already implemented in single ID deletion (`BKE_id_delete` & co), in the underlying private `id_free`. But this is skipped in `no main` case. which is used by the batch deletion code for performance optimizations.
