Fix calculation of param/result types in wit-bindgen (#5622)

This commit fixes a bug in the `bindgen!` macro for components where
previously the `param` and `result` properties weren't properly
calculated depending on the structure of the type and which types were
visited in which order. This is simplified to use a `LiveTypes`
structure from the `wit-parser` crate and relies on that to do necessary
recursion.
