azure: Convert Windows installations scripts to `bash`
Looks like `script`, which uses `cmd.exe`, doesn't have fail-fast
behavior and if a leading command fails the script doesn't actually fail
so long as the last command succeeds. We instead want the opposite
behavior where if any step fails the whole script fails.
I don't really know `cmd.exe` that well, nor powershell, so I've opted
to move everything to `bash` which should be a good common denominator
amongst all platforms to work with. Additionally I know that `set -e`
works to cause scripts to fail fast.
Closes #64551

Note that some scripts remain as `script` since they don't appear to
work in` bash`. I'm not really sure why but I reorganized them slightly
to have the "meaty command" run at the end.

This commit changes our CI to use two separate IAM users to
authenticate with AWS:
* ci--rust-lang--rust--sccache: has access to the rust-lang-ci-sccache2
S3 bucket and its credentials are available during the whole build.
* ci--rust-lang--rust--upload: has access to the rust-lang-ci2 S3 bucket
and its credentials are available just during the upload step.
The new tokens are available in the `prod-credentials` library.

azure: Disable more LLVM/debug assertions in
This commit disables LLVM/debug assertions in our 5 slowest builders:
* i686-gnu
* i686-gnu-nopt
* i686-msvc-1
* i686-msvc-2
* x86_64-msvc-cargo
This is reducing the amount of test coverage for LLVM/debug assertions,
but we're just unfortunately running out of time on CI too many times.
Some test builds have shown that i686-gnu drops nearly an hour of CI
time by disabling these two assertions. Perhaps when we eventually get
4-core machines we can reenable these, but for now turn them off and
hook them up to the tracking issue at #59637 which will ideally be
repurposes to tracking all of these.

GitHub only allows people explicitly listed as collaborators on the
repository or who commented on the issue/PR to be assignees, failing to
create the issue if non-assignable people are assigned.
This adds an extra check on CI to make sure all the people listed as
tool maintainers can be assigned to toolstate issues. The check won't be
executed on PR builds due to the lack of a valid token.

ci: move linkcheck from mingw-2 to mingw-1
Running UI tests now takes a huge amount of time on mingw builders
(between 40 and 50 minutes), with mingw-1 builders taking even an hour
less to finish than mingw-2. This PR moves linkcheck from mingw-2 to
mingw-1, removing between 10 and 20 minutes of runtime on the -2
builders.

Currently mirrors are stored in the rust-lang-ci2 S3 bucket along with
CI toolchains. This is problematic for multiple reasons:
- CI IAM credentials are allowed to both edit and delete those files.
A malicious user gaining access to those credentials would be able to
change our mirrored dependencies, possibly backdooring the compiler.
- Contents of the rust-lang-ci2 bucket are disposable except for the
mirrors' content. When we implement backups for S3 buckets we'd have
to replicate just that part of the bucket, complicating the backup
logic and increasing the chance of mistakes. A standalone bucket will
be way easier to backup.
This commit switches our CI to use the new rust-lang-ci-mirrors bucket.
