Cleanup: Rename `ModSep` to `PathSep`

`::` is usually referred to as the *path separator* (citation needed).

The existing name `ModSep` for *module separator* is a bit misleading since it in fact separates the segments of arbitrary path segments, not only ones resolving to modules. Let me just give a shout-out to associated items (`T::Assoc`, `&lt;Ty as Trait&gt;::function`) and enum variants (`Option::None`).

Motivation: Reduce friction for new contributors, prevent potential confusion.
