0025405: STL reader doesn't keep shared nodes

Browse Source 
An improved RWSTL::ReadFile() method + a draw-command returning the number of nodes and triangles for a MeshVS_Mesh object based on STL mesh data source.

An indexed map of points is replaced by a CellFilter of XYZ objects already implemented in BRepBuilderAPI.
Also, BRepBuilderAPI_VertexInspector became exported for TKTopAlgo library (Standard_EXPORT is added for the methods of this class).

Standard_EXPORT is removed for in-line methods of BRepBuilderAPI_VertexInspector

Test-case for issue #25405

Update of test-cases, according to new behavior
