Fix T59338: Blender crashes immediately after loading attached file in ~80% of my attempts.

Issue was a concurrent modification of an evaluated mesh by two
other meshes using it as source for custom normals data transfer.

Note that this fixes the crash (modifiers are strictly forbidden to modify
any data besides their own!), but now will have to add a new CD type to
be able to specifically request 'computed' clnors data layer, and not
only 'encoded' one, for source mesh...
