[Python] Fix generic type parameter handling for class methods and ResizeArray Seq compatibility

[dbrattli]

• Fix FSharpList and other generic classes to not redeclare class-level type parameters on methods like GetEnumerator and __iter__
• Add class generic parameters to ScopedTypeParams context before processing attached members
• Filter out class-level generics from method type parameters in calculateTypeParams
• Wrap ResizeArray (Python list) arguments with to_enumerable() in Seq module functions for type compatibility
