David Peter da4be789ef [ty] Ignore ClassVar declarations when resolving instance members (#18241) ...

## Summary

Make sure that the following definitions all lead to the same outcome
(bug originally noticed by @AlexWaygood)

```py
from typing import ClassVar

class Descriptor:
    def __get__(self, instance, owner) -> int:
        return 42

class C:
    a: ClassVar[Descriptor]
    b: Descriptor = Descriptor()
    c: ClassVar[Descriptor] = Descriptor()

reveal_type(C().a)  # revealed: int  (previously: int | Descriptor)
reveal_type(C().b)  # revealed: int
reveal_type(C().c)  # revealed: int
```
