shiboken6: Generate rich comparison for smart pointers

Add the pointee class to the GeneratorContext for smart pointers
and generate a comparison operator for the pointee.
Use the pointee's comparison operators if there are any; else
generate a simple equality check based on pointee address.

[ChangeLog][shiboken6] Comparison operators for pointees of
smart pointers are now generated.

Fixes: PYSIDE-1711
