Rollup merge of #76078 - jyn514:no-disambiguator, r=manishearth

Remove disambiguators from intra doc link text

Closes https://github.com/rust-lang/rust/issues/65354.
r? @Manishearth

The commits are mostly atomic, but there might be some mix between them here and there. I recommend reading 'refactor ItemLink' and 'refactor RenderedLink' on their own though, lots of churn without any logic changes.
