C#: Sync Plane with Core

[raulsntos]

• Add Plane(Vector3) constructor.
  • Added to Core in Swap args of Plane(point, normal) constructor #37842.
  • In C# implemented as an overload instead of default parameter value to be able to use a different documentation summary.
• Rename IntersectRay to IntersectsRay.
  • It always had the s in Core.
• Rename IntersectSegment to IntersectsSegment.
  • It always had the s in Core.
• Replace Center property with GetCenter method.
  • This matches the other C# structs that also implement a GetCenter method (AABB, Rect2, and Rect2i).
  • Also renaming this in Core in a separate PR: Rename center method to get_center in Plane. #71474.
  • Alternatively, since the implementation is cheap enough we could decide to replace all the GetCenter methods with Center properties instead¹.

1. This is not possible in GDScript because it doesn't support readonly properties but in C# we can. ↩

Replace Center property with GetCenter method.

@akien-mga Would it be OK to also rename the method in Core, or is it too late? To fix the inconsistency with AABB, Rect2, and Rect2i.

Ah yes, a method named center() is pretty weird. Should definitely get get_center().
