Auto merge of #116958 - oli-obk:coro, r=pnkfelix
rename Generator to Coroutine implements https://github.com/rust-lang/compiler-team/issues/682 While I did an automated replacement, I went through all changes manually to avoid renaming things like "id generators", "code generator", ... I renamed files where that was necessary due to the contents referring to the crate name itself (mir opt, codegen or debuginfo tests), or required by tidy (feature gate docs) * [x] rename various remaining abbreviated references to generators. * [x] rename files * [x] rename folders * [x] add renamed feature: `generators`, ... r? `@ghost`
