Fix #30152: Several drag and drop of image on mesh crashes

Issue was caused by making and loading editMesh in drop_named_image_invoke,
which lead to freeing/changing pointers used by CustomData layers. Some of
this pointers might be used by DerivedMesh, so we need to update DerivedMesh
after loading EditMesh.
