Rollup merge of #147809 - GuillaumeGomez:fix-rustdoc-passes, r=fmease

rustdoc: Fix passes order so intra-doc links are collected after stripping passes

Fixes regression I introduced in #147153.

This PR puts back the intra-doc link collecting pass after the stripping items pass, preventing lints to be emitted on non-visible items.

Although, might be nice to add a way to change this behaviour. To be discussed later on.
