[ty] Improve rendering of default values for function args (#22010) ## Summary We're actually quite good at computing this but the main issue is just that we compute it at the type-level and so wrap it in `Literal[...]`. So just special-case the rendering of these to omit `Literal[...]` and fallback to `...` in cases where the thing we'll show is probably useless (i.e. `x: str = str`).
