[ty] Make special cases for subscript inference exhaustive (#22035) ## Summary Fixes https://github.com/astral-sh/ty/issues/2015. We weren't recursing into the value of a type alias when we should have been. There are situations where we should also be recursing into the bounds/constraints of a typevar.
