[red-knot] Fix recording of negative visibility constraints (#17731)
## Summary

We were previously recording wrong reachability constraints for negative
branches. Instead of `[cond] AND (NOT [True])` below, we were recording
`[cond] AND (NOT ([cond] AND [True]))`, i.e. we were negating not just
the last predicate, but the `AND`-ed reachability constraint from last
clause. With this fix, we now record the correct constraints for the
example from #17723:

```py
def _(cond: bool):
    if cond:
        # reachability: [cond]
        if True:
            # reachability: [cond] AND [True]
            pass
        else:
            # reachability: [cond] AND (NOT [True])
            x
```

closes #17723 

## Test Plan

* Regression test.
* Verified the ecosystem changes
