Fix: Mesh SoA format conversion skips versioning

Converting to the SoA format (T95965) immediately when reading meshes
means that none of the changes from versioning would be applied first.
This means important fixes like f14995aba70a aren't properly applied,
so modifications could be done to invalid CustomData. To fix this, move
the SoA changes into versioning code, in a new versioning_400.cc file.
