Ibraheem Ahmed 2ce3aba458 [ty] Use annotated parameters as type context (#20635) ...

## Summary

Use the type annotation of function parameters as bidirectional type
context when inferring the argument expression. For example, the
following example now type-checks:

```py
class TD(TypedDict):
    x: int

def f(_: TD): ...

f({ "x": 1 })
```
