Gate GHA on everything but macOS
The macOS spurious failure started happening again. As we discussed during the infra team meeting, this gates on everything but macOS.
r? @Mark-Simulacrum
In our GitHub Actions setup macOS is too unreliable to gate on it, but
the other builders work fine. This commit splits the macOS builders into
a separate job (called auto-fallible), allowing us to gate on the auto
job without failing due to macOS spurious failures.

Tweak `::` -> `:` typo heuristic and reduce verbosity
Do not trigger on correct type ascription expressions with trailing
operators and _do_ trigger on likely path typos where a turbofish is
used.
On likely path typos, remove note explaining type ascription.
Clean up indentation.

Avoid "blacklist"
Other terms are more inclusive and precise.
Clippy still has a lint named "blacklisted-name", but renaming it would
be a breaking change, so is left for future work.
The target configuration option "abi-blacklist" has been depreciated and
renamed to "unsupported-abis". The old name continues to work.

Eliminate confusing "globals" terminology.
There are some structures that are called "globals", but are they global
to a compilation session, and not truly global. I have always found this
highly confusing, so this commit renames them as "session globals" and
adds a comment explaining things.
Also, the commit fixes an unnecessary nesting of `set()` calls

r? @Aaron1011
Use relative path for local links to primitives
Else, links to `char::foo` would point into `/path/to/src/libcore/std/primitive.char.html#method.foo`.
Split out from #73804.
Use for<'tcx> fn pointers in Providers, instead of having Providers<'tcx>.
In order to work around normalization-under-HRTB (for `provide!` in `rustc_metadata`), we ended up with this:
```rust
struct Providers<'tcx> {
type_of: fn(TyCtxt<'tcx>, DefId) -> Ty<'tcx>,
// ...
}
```
But what I initially wanted to do, IIRC, was this:
```rust
struct Providers {
type_of: for<'tcx> fn(TyCtxt<'tcx>, DefId) -> Ty<'tcx>,
// ...
}
```
This PR moves to the latter, for the simple reason that only the latter allows keeping a `Providers` value, or a subset of its `fn` pointer fields, around in a `static` or `thread_local!`, which can be really useful for custom drivers that override queries.
(@jyn514 and I came across a concrete usecase of that in `rustdoc`)
The `provide!` macro in `rustc_metadata` is fixed by making the query key/value types available as type aliases under `ty::query::query_{keys,values}`, not just associated types (this is the first commit).

Fix x.py test for librustc crates.
#73352 introduced a bug where `x.py test src/librustc_ast` would fail to actually run the tests. The issue is that `krate` and `all_krates` were changed to return relative paths. This caused the code to do a test of "relative_path ends with absolute path" which is always false. The solution is to swap that around.
The change to `Crate` isn't necessary, it just simplifies the code and makes it uniform with `CrateLibrustc`.
There don't seem to be any other compiletests that are 1) building a standalone "no_core" create and then 2) trying to link against it. There seems to be a platform-specific limitation in doing so:
```

```
Possibly this could be resolved by adding a `__DllMainCRTStartup` or `__DllMainCRTStartup@12` symbol in an architecture- and platform-specific way.

Fix occasional bootstrap panic in docs.
I am occasionally running into this panic when running `x.py`:
> thread 'main' panicked at 'source "/Users/eric/Proj/rust/rust/build/x86_64-apple-darwin/md-doc/unstable-book" failed to get metadata: No such file or directory (os error 2)', src/build_helper/lib.rs:173:19
I have not been able to figure out the exact sequence of commands that leads to this error (I tried for quite a while to reproduce it). I think it may involve updating my tree, but I am uncertain. An artificial way to trigger it is to build the documentation, and then delete the `md-doc` directory manually.
The cause is that bootstrap does a "dry run" before every command, and in this case `up_to_date` panics because the destination exists (`build/x86_64-apple-darwin/doc/unstable-book/index.html `) but the source does not (`build/x86_64-apple-darwin/md-doc/unstable-book`).
I am uncertain if it is important that the last line `builder.run(…)` needs to be called during the dry run. This patch seems to fix the issue, though.
