[red-knot] Attribute access on intersection types (#16665)
## Summary

Implements attribute access on intersection types, which didn't
previously work. For example:

```py
from typing import Any

class P: ...
class Q: ...

class A:
    x: P = P()

class B:
    x: Any = Q()

def _(obj: A):
    if isinstance(obj, B):
        reveal_type(obj.x)  # revealed: P & Any
```
