[Topology.Mapping] Support MeshTopology as output in Tetra2TriangleTopologicalMapping

[alxbilger]

The Pull Request introduces enhancements and refactoring in the Tetra2TriangleTopologicalMapping and TopologicalMapping classes to improve topology modifier handling. The changes replace the usage of direct pointers with a SingleLink, improve error logging, refactor validation checks for input/output topology types, and update how topological operations are handled dynamically.

Main Changes

• Introduction of SingleLink:
  • A new SingleLink named l_topologyModifier is added to replace m_outTopoModifier, improving link-handling consistency.
• Error Handling Improvements:
  • Refactoring of initialization and error messaging to ensure clearer runtime feedback regarding missing components (TriangleSetTopologyModifier).
• Separation of Validation Logic:
  • New functions introduced (checkMappingInputType, checkMappingOutputType, compareInputTopologyType, compareOutputTopologyType) break down checkTopologyInputTypes for better reusability and readability in TopologicalMapping.cpp.
• Code Updates in Tetra2TriangleTopologicalMapping:
  • Replacing direct calls to m_outTopoModifier with l_topologyModifier for operations such as adding/removing triangles, edges, or points.
  • Additional checks and graceful handling when l_topologyModifier is not set.
