Auto merge of #83738 - jyn514:only-load-some-crates, r=petrochenkov
rustdoc: Don't load all extern crates unconditionally Instead, only load the crates that are linked to with intra-doc links. This doesn't help very much with any of rustdoc's fundamental issues with freezing the resolver, but it at least fixes a stable-to-stable regression, and makes the crate loading model somewhat more consistent with rustc's. I tested and it unfortunately does not help at all with #82496. Closes #68427. Let me know if you want me to open a separate issue for not freezing the resolver. r? `@petrochenkov` cc `@eddyb` `@ollie27`
