fix [Feat] better behavior for getattr() w/ literal attribute names #4477

[asukaminato0721]

Summary

Fixes #4477

Literal-name getattr now reuses normal attribute inference for class instances instead of always falling back to typeshed’s Any.

It still runs the ordinary builtin call validation first, then only overrides the return type when the call is getattr(obj, "literal", default?), the receiver is a ClassType, and the attribute lookup succeeds.
