Rollup merge of rust-lang#76115 - calebcartwright:parser-fn-visibility, r=matklad

Restore public visibility on some parsing functions for rustfmt

In rust-lang#74826 the visibility of several parsing functions was reduced. However, rustfmt is an external consumer of some of these functions as well and needs the visibility to be public, similar to other elements in rustc_parse such as `parse_ident`
