Add versioning for 2.90 files that may have invalid mesh 

rBf2d26409e83b fixed a serious problem with invalid mesh after an
operation with the extrude manifold.

Since BKE_mesh_validate_arrays is a slow operation, the chosen
interval between versions is relatively small and also only the
mentioned invalid mesh problem is tested.
