Lab - Fixes for C3t3 IO in `.vtu` format (#8757) 

## Summary of Changes
* Subdomain indices can be 0 or negative, just the cells with subdomain
0 are not added to the complex.
* make binary status of the opened `ofstream` consistent with call to
`CGAL::IO::output_to_vtu()`

## Release Management

* Affected package(s): CGAL Lab
* License and copyright ownership: unchanged
