Auto merge of #10404 - dnbln:feat/unused_enumerate_index, r=blyxyas
Add `unused_enumerate_index` lint

A lint for unused `.enumerate()` indexes (`for (_, x) in iter.enumerate()`).

I wasn't able to find a `rustc_span::sym::Enumerate`, so the code for checking that it's the correct `Enumerate` iterator is a bit weird.

---

changelog: New lint: [`unused_enumerate_index`]: A new lint for checking that the indexes from `.enumerate()` calls are used.
