Respect the return qualifier for attributes on class methods

[DragonSA]

Description

Attributes attached to the return value of a class method (e.g. [<return: NotNull>]) were instead being attached to the method itself. This did not happen for functions (let bind). I refactored the logic out of TcNormalizedBinding (used by TcLetBinding and used that in AnalyzeAndMakeAndPublishRecursiveValue.

Fixes #19020
