Mesh_3 - Mesh_criteria_3 cleaning

[janetournois]

Summary of Changes

As spotted in PR #7532, there were named parameters available in the constructor of Mesh_criteria_3 that had never been documented or used.

This commit, written before the publication of Mesh_3 with features in CGAL-3.8, removed the documentation of these criteria before their publication.

Release Management

• Affected package(s): Mesh_3
• License and copyright ownership: unchanged

@lrineau I also added the use of get_parameter_reference() for all the parameters that may be a MeshDomainField_3 (distance and size)

Most probably responsible for errors in (periodic) Mesh_3 test/ex in CGAL-6.0-Ic-112

My last commit 7fdc36d highlights the fact that it was possible to use facet_size together with facet_sizing_field and sizing_field, which was imho confusing, but could still be considered as a feature.
@lrineau do you still agree that we should keep only facet_size (and other dimensions counterparts)?
