Jack O'Connor e245c1d76e [ty] narrow tagged unions of TypedDict (#22104) ...

Identify and narrow cases like this:

```py
class Foo(TypedDict):
    tag: Literal["foo"]

class Bar(TypedDict):
    tag: Literal["bar"]

def _(union: Foo | Bar):
    if union["tag"] == "foo":
        reveal_type(union)  # Foo
```
