Rollup merge of #57343 - Xanewok:querify-access-levels, r=nikomatsakis

Calculate privacy access only via query

Initially converted to query in https://github.com/rust-lang/rust/commit/a9f6babcda1479f4e5566d1aadbf9a0d99aa3182 and then changed to respect dependencies https://github.com/rust-lang/rust/commit/8281e883dd12260f00ce650aa8824507d9c447af.

I did this as an effort to prune `CrateAnalysis` from librustc_save_analysis, with the only thing remaining being the glob map (`name` is unused, existing `crate_name` is exposed in the compiler passes, instead).

Since calculating the glob map is opt-in, it'd be great if we could calculate that on-demand. However, it seems that it'd require converting resolution to queries, which I'm not sure how to do yet.

In an effort to get rid of `CrateAnalysis` altogether, could we try unconditionally calculating the glob_map in the resolver, thus completely removing `CrateAnalysis` struct, and doing a perf run?

r? @nikomatsakis

cc @petrochenkov do you have any idea how/if at all could we querify the resolver? I've stumbled upon a comment that's ~3? years old at the moment, so I'm guessing things might have changed and it actually may be feasible now. https://github.com/rust-lang/rust/blob/fe0c10019d7ee96909cc42cc265ef999a6b5dd70/src/librustc_driver/driver.rs#L589-L593
