Rollup merge of rust-lang#124542 - CBSpeir:diagnostic-item-enumerate-…

…method, r=scottmcm Add diagnostic item for `std::iter::Iterator::enumerate` Adds a diagnostic item for the `std::iter:Iterator::enumerate` trait method. This change, along with PR rust-lang#124308, will be used by the clippy `unused_enumerate_index` lint to move away from paths to using diagnostic items. see: rust-lang/rust-clippy#5393
