Add hash eq and neq operations to TShape

[JohannesVerherstraeten]

Fixes the issue where the __hash__, __eq__ and __neq__ operators of TopoDS_TShape are not implemented, giving unexpected results like:

from OCC.Core.BRepPrimAPI import BRepPrimAPI_MakeBox

shape_1 = BRepPrimAPI_MakeBox(10, 20, 30).Shape()

shape_1.TShape() == shape_1.TShape()    # Expected: True, but is False
hash(shape_1.TShape()) == hash(shape_1.TShape())    # Expected: True, but is False

This fix allows properly comparing TopoDS_TShapes and using them in sets/dictionaries.

Summary by Sourcery

Implement hash, equality, and inequality operators for TopoDS_TShape to fix comparison issues and enable usage in sets and dictionaries, and add corresponding tests.

New Features:

• Implement __hash__, __eq__, and __neq__ operators for TopoDS_TShape to enable proper comparison and usage in sets and dictionaries.

Tests:

• Add tests for the __hash__, __eq__, and __neq__ operators of TopoDS_TShape to ensure correct functionality.

Thank you @JohannesVerherstraeten for this contribution. It is strange the _neq__ or eq operators are not handled by default for the TopoDS_TShape class, all c++ classes that implement the != operator should benefit from this addition.
