Daniel P. Berrangé c70fe3b148 ci: replace x86_64 macos-11 with aarch64 macos-12
The Cirrus CI service has announced the intent to discontinue
support for x86_64 macOS CI runners. They already have aarch64
runners available and require all projects to switch to these
images before Jan 1st 2023. The different architecture is
merely determined by the image name requested.

For aarch64 they only support macOS 12 onwards. At the same
time our support policy only guarantees the most recent 2
major versions, so macOS 12 is already technically our min
version.

Cirrus CI integration
=====================

GitLab CI shared runners only provide a docker environment running on Linux.
While it is possible to provide private runners for non-Linux platforms this
is not something most contributors/maintainers will wish to do.

To work around this limitation, we take advantage of `Cirrus CI`_'s free
offering: more specifically, we use the `cirrus-run`_ script to trigger Cirrus
CI jobs from GitLab CI jobs so that Cirrus CI job output is integrated into
the main GitLab CI pipeline dashboard.

There is, however, some one-time setup required. If you want FreeBSD and macOS
builds to happen when you push to your GitLab repository, you need to

* set up a GitHub repository for the project, eg. ``yourusername/qemu``.
  This repository needs to exist for cirrus-run to work, but it doesn't need to
  be kept up to date, so you can create it and then forget about it;

* enable the `Cirrus CI GitHub app`_  for your GitHub account;

* sign up for Cirrus CI. It's enough to log into the website using your GitHub
  account;

* grab an API token from the `Cirrus CI settings`_ page;

* it may be necessary to push an empty ``.cirrus.yml`` file to your github fork
  for Cirrus CI to properly recognize the project. You can check whether
  Cirrus CI knows about your project by navigating to:

  ``https://cirrus-ci.com/yourusername/qemu``

* in the *CI/CD / Variables* section of the settings page for your GitLab
  repository, create two new variables:

  * ``CIRRUS_GITHUB_REPO``, containing the name of the GitHub repository
    created earlier, eg. ``yourusername/qemu``;

  * ``CIRRUS_API_TOKEN``, containing the Cirrus CI API token generated earlier.
    This variable **must** be marked as *Masked*, because anyone with knowledge
    of it can impersonate you as far as Cirrus CI is concerned.

  Neither of these variables should be marked as *Protected*, because in
  general you'll want to be able to trigger Cirrus CI builds from non-protected
  branches.

Once this one-time setup is complete, you can just keep pushing to your GitLab
repository as usual and you'll automatically get the additional CI coverage.
