Coding - Remove unused typedefs and includes, replace with forward declarations (#971)

- Deleted TopoDS_ListOfShape.hxx and removed its references in various files.
- Replaced instances of TopoDS_ListOfShape with NCollection_List in TopoDS_Builder, TopoDS_Iterator, and TopoDS_TShape.
- Updated CMake files to exclude TopoDS_ListOfShape from the build.
- Removed Geom2dConvert_SequenceOfPPoint and its usages, replacing them with NCollection_Sequence.
- Cleaned up Select3D and SelectMgr modules by removing Select3D_EntitySequence, Select3D_IndexedMapOfEntity, and SelectMgr_IndexedMapOfOwner.
- Adjusted includes in various files to use NCollection types instead of removed classes.
- Overall, this commit streamlines the codebase by eliminating unused types and reducing dependencies.
