Migrate rustc_codegen_llvm to SessionDiagnostics
WIP: Port current implementation of diagnostics to the new SessionDiagnostics.
Part of #100717

Const Compare for Tuples
Makes the impls for Tuples of ~const `PartialEq` types also `PartialEq`, impls for Tuples of ~const `PartialOrd` types also `PartialOrd`, for Tuples of ~const `Ord` types also `Ord`.
behind the `#![feature(const_cmp)]` gate.
~~Do not merge before #104113 is merged because I want to use this feature to clean up the new test that I added there.~~

Don't intra linkcheck reference
This removes the reference from the intra-doc link checks. This causes problems if any of the reference content needs to change, it causes the linkchecker to break. The reference has its own broken link check (https://github.com/rust-lang/reference/tree/master/style-check) which uses pulldown-cmark on the source to find actual broken links (instead of false-positives like this regex does).
I think the intra-doc link check could potentially be removed completely, since I think rustdoc is now checking for them well enough. However, it may serve as a decent regression check.
Remove allow(rustc::potential_query_instability) in rustc_trait_selection

This PR needs to be benchmarked to check for regressions.
Refactor build-manifest to minimize the number of changes needed to add a new component
- Add all components to `PkgType`
- Automate functionality wherever possible, so functions often don't have to be manually edited
- Where that's not possible, use exhaustive matches on `PkgType` instead of adding individual strings.
- Add documentation for how to add a component. Improve the existing documentation for how to test changes.
I tested locally that this generates an identical manifest before and after my change, as follows:
```sh
git checkout d44e14225a
cargo +nightly run --manifest-path src/tools/build-manifest/Cargo.toml build/dist build/manifest-before 1970-01-01 http://example.com nightly
git checkout refactor-build-manifest
cargo +nightly run --manifest-path src/tools/build-manifest/Cargo.toml build/dist build/manifest-before 1970-01-01 http://example.com nightly
sort -u build/manifest-before/channel-rust-nightly.toml | diff - <(sort -u build/manifest-after/channel-rust-nightly.toml)
```
I then verified by hand that the differences before sorting are inconsequential (mostly targets being slightly reordered).
The only change in behavior is that `llvm-tools` is now properly renamed to `llvm-tools-preview`:
```
; sort -u build/manifest-before/channel-rust-nightly.toml | diff - <(sort -u build/manifest-after/channel-rust-nightly.toml)
784a785
> [renames.llvm-tools]
894a896
> to = "llvm-tools-preview"
```
This is based on https://github.com/rust-lang/rust/pull/102241 and should not be merged before.
