Switch from `derivative` to `derive-where`

This is a part of the effort to get rid of `syn 1.*` in compiler's dependencies: #109302

Derivative has not been maintained in nearly 3 years[^1]. It also depends on `syn 1.*`.

This PR replaces `derivative` with `derive-where`[^2], a not dead alternative, which uses `syn 2.*`.

A couple of `Debug` formats have changed around the skipped fields[^3], but I doubt this is an issue.
