The `aarch64-pc-windows-msvc` target is on the path to being promoted to
Tier 1: <https://github.com/rust-lang/rfcs/pull/3817>
Adding Arm64 Windows runners will catch any potential issues in Cargo
before changes are merged in, instead of waiting for the Cargo submodule
to be updated.
RFC 3841 has merged, and x86_64-apple-darwin will be demoted to tier-2
in 1.90.0. In Cargo we usually run test against tier-1 platforms, so
x86_64-apple-darwin should be removed.
Also, that target platform is often the slowest one in CI,
we are happy to remove it to save us a couple of minutes.

GitHub Actions has Windows SDK pre-installed,
so cdb should be available at that path always.
Additionally, this adds a new CI job for windows-msvc nightly toolchain
I'm not certain, but I do not believe it was intentional in https://github.com/rust-lang/cargo/pull/15000 to allow the `schema` job to fail. This adds it to the required passing list.
Due to rendering limits with GitHub's markdown renderer, we're moving
the changelog to the cargo book where it can be statically served under
our control.
In rust-lang/cargo#14183 Cargo starts bailing out if the `metadata.std`
field in a target spec JSON is set to `false`.
This is problematic because std for some targets are actually buildable
even they've declared as std-unsupported.
This patch removes the hard error, and instead determines the required
root crates by the `metadata.std` field. That is to say, if a target
is explicitly declared as `std: false`, `-Zbuild-std` will build `core`
and `compiler-builtins` only, no `std` will be built.
This patch doesn't change the behavior of `-Zbuild-std` with explicit
crates set. For example `-Zbuild-std=std` will force building `std`.

The tests are intended to spot check that shell completions are
registered correctly. That is a low change, low risk area. For shell
integration, we're relying on `clap_complete`s tests.
For our own candidates, we should test the candidate generation
directly, rather than end-to-end.
This reverts parts of commit e7ca9bec80ab5c010c1a84690816da7b64008257, reversing
changes made to bd5f32bb1c7ca273b5d86815bf0ae4adba59ddd8.
Fixes#14545
We will be promoting aarch64-apple-darwin to tier 1 soon via
https://github.com/rust-lang/rust/pull/128592. This updates our CI
so that aarch64-apple-darwin runs the full test suite on nightly to
keep this in-line with tier-1 support.
This also removes the x86_64 stable macos job and replaces it with
aarch64, mainly because aarch64 runs much faster, and presumably
x86_64 support will go away some day.
This adds some tests to ensure that the database used in the global
cache tracker stays compatible across versions. These tests work by
using rustup to run both the current cargo and the stable cargo, and
verifying that when switching versions, everything works as expected.
ci/contrib: use separate concurrency group
Run the contrib workflow in its own concurrency group to avoid multiple runs causing conflicting git pushes.
The contrib workflow pushes to the gh-pages branch, and thus is not safe to be run multiple times in parallel. Given that github-actions can stall workflow runs for quite some time, multiple executions can overtake each other. By using concurrency groups, all workflow runs will wait until previous runs completed.
Given that the workflow uses orphan-branches and forced pushes, conflicting workflows will not fail, but might produce outdated data if they overtake each other.
We explicitly disable cancellation to get better diagnostics and more easily find the first possible run that failed. Since these workflow runs are rather fast, and only run on master, cancellation seems not necessary.

The current contrib deploy-hook fails if there is no `gh-pages` branch.
Change the CI order to disregard the old `gh-pages` branch first.
The `contrib` deploy-hook always creates a fresh `gh-pages` commit and
pushes it out. However, currently it relies on the old `gh-pages` branch
to exist, since it does not ignore errors when pruning it. Fortunately,
the code always creates a new orphan branch, since it does not want to
keep history for deployments. Therefore, we can simply use:
`git worktree --orphan -B <branch> <path>`
This will ensure to always create an orphan branch named `<branch>`, and
override an existing branch if it exists (see `-b` vs `-B`). Hence,
there is no need for us to prune the old branch, anymore.
Since we will recreate the branch on every push, we have to explicitly
specify the remote to push to. We no longer set up branch tracking.
