cake-monotone f463fa7b7c [red-knot] Narrowing For Truthiness Checks (if x or if not x) (#14687) ...

## Summary

Fixes #14550.

Add `AlwaysTruthy` and `AlwaysFalsy` types, representing the set of objects whose `__bool__` method can only ever return `True` or `False`, respectively, and narrow `if x` and `if not x` accordingly.


## Test Plan

- New Markdown test for truthiness narrowing `narrow/truthiness.md`
- unit tests in `types.rs` and `builders.rs` (`cargo test --package
red_knot_python_semantic --lib -- types`)
