0025039: Improvement of code structure of general and supporting tools implemented in BRepMesh

Removed CDL declarations; Data collections are replaced by NCollections; Small code refactoring.
Remove definition of BRepMesh class. Code refactoring of BRepMesh_IncrementalMesh.
Function BRepMesh_Write storing BRepMesh_DataStructureOfDelaun to BRep file is added for debug needs.
Static method BRepMesh_GeomTool::IntLinLin has been added to eliminate code duplications in BRepMesh_Dealun and BRepMesh_CircleTool.
BRepMesh_CircleTool simplified method to find circumcircle.

Fix merging conflicts
Remove redundant function
Fix compilation warning on MacOS
Revert changes occurred during rebase
Resolved merging conflicts
Use parallel flag with BRepMesh_FastDiscret
