Douglas Creager 0fb94c052e [ty] Infer parameter specializations of generic aliases (#18021) ...

This updates our function specialization inference to infer type
mappings from parameters that are generic aliases, e.g.:

```py
def f[T](x: list[T]) -> T: ...

reveal_type(f(["a", "b"]))  # revealed: str
```

Though note that we're still inferring the type of list literals as
`list[Unknown]`, so for now we actually need something like the
following in our tests:

```py
def _(x: list[str]):
    reveal_type(f(x))  # revealed: str
```
