[ty] Handle typevars that have other typevars as a default (#17956)
It's possible for a typevar to list another typevar as its default
value:

```py
class C[T, U = T]: ...
```

When specializing this class, if a type isn't provided for `U`, we would
previously use the default as-is, leaving an unspecialized `T` typevar
in the specialization. Instead, we want to use what `T` is mapped to as
the type of `U`.

```py
reveal_type(C())  # revealed: C[Unknown, Unknown]
reveal_type(C[int]())  # revealed: C[int, int]
reveal_type(C[int, str]())  # revealed: C[int, str]
```

This is especially important for the `slice` built-in type.
