Rollup merge of #123001 - Alexendoo:check-attributes, r=oli-obk

Rename `{enter,exit}_lint_attrs` to `check_attributes{,_post}`

Several places in Clippy want to check all the attributes of a node, we end up using `hir().attrs()` from several different `check_` functions (e.g. [in our doc lints](https://github.com/rust-lang/rust-clippy/blob/95c62ffae9bbce793f68a6f1473e3fc24af19bdd/clippy_lints/src/doc/mod.rs#L396)) but this is error prone, we recently found that doc lints weren't triggering on struct fields for example

I went to add a `check_attributes` function but realised `enter_lint_attrs` is already this, the rename is to encourage their use

Also removes `LateContextAndPass::visit_attribute` since it's unused - `visit_attribute` for HIR visitors is only called by `hir().walk_attributes()` which lint passes do not use
