Objects in Geometry should allow comparing them to objects of other types (e.g. None)

[Brow71189]

Right now, comparing any of the objects in Geometry to objects of a different type fails. The eq and ne magic methods in these objects should be implemented in a way that the comparison does not fail but returns False.

I will add regression coverage and make the Geometry value objects return False / True for equality and inequality comparisons with unrelated values, while preserving comparisons with supported coordinate tuples.
