[Core][Geometries] Adding to base class GetIntersectionPoints

[loumalouomega]

📝 Description

Closes #10470. WE have the HasIntersection method, but no method to get the actual intersection points. This method adds the corresponding method is some geometries (where the intersection is already implemented as auxiliary utilities). Using a std::vector, so the number of intersection points can be arbitrary, between 0 (no intersection), to the required size for the specific geometry combination

🆕 Changelog

• Adding to base class GetIntersectionPoints
• Adding GetIntersectionPoints to lines
• Adding GetIntersectionPoints to triangles
• Expose python
• Adding line tests
• Test for triangle

Minor comments, I do not like that the code is duplicated in both classes. but I guess a possible fix for that would go much further than the scope of this PR. We could maybe have a line and triangle base classes to avoid such duplications

[ddiezrod]

We were discussing this today in @KratosMultiphysics/implementation-committee , in principle we agree this is a nice addition to the geometry classes. Only please, to avoid code duplication, try to move the common code to intersection_utilties. @loumalouomega

Please refer to the #10470 for the discussion we made about this one.

@pooyan-dadvand can we delegate decisions on this to you? we guess you are following this more closely with Vicente

@pooyan-dadvand ping, can you take this over?
