[ty] Bare `ClassVar` annotations (#15768)
## Summary

It was recently clarified in the [typing
spec](https://typing.python.org/en/latest/spec/class-compat.html#classvar)
that bare `ClassVar` annotations are allowed. For annotated assignments
with a right hand side value, the spec requires type checkers to infer
the type as something "to which [the] value is assignable". For a value
of `2`, the spec suggests `int`, `Literal[2]`, or `Any` as examples.
Here, we choose `Unknown | Literal[2]` instead, conforming with out
usual treatment of attribute types.
