Caused by 84c7684871.
Previously we could count on adding the attributes to the result mesh
not failing. Now, since the vertex group names are copied, they might
fail because a name would cause the attribute to already exist with a
float type on the point domain, which might not match the most
complex domain/type we'd use otherwise.
The fix is to only create attributes as vertex groups if the domain and
type combination from all the input meshes is correct.
