[ty] typecheck dict methods for TypedDict (#19874)
## Summary

Typecheck `get()`, `setdefault()`, `pop()` for `TypedDict`

```py
from typing import TypedDict
from typing_extensions import NotRequired

class Employee(TypedDict):
    name: str
    department: NotRequired[str]

emp = Employee(name="Alice", department="Engineering")

emp.get("name")
emp.get("departmen", "Unknown")
emp.pop("department")
emp.pop("name")
```
