Cirrus: Publish binary artifacts on success

In general continuous-delivery (CD) tends to pair well with CI.  More
specifically, there is a need for some reverse-dependency CI testing in
netavark/aardvark-dns.  In all cases, the download URL needs to remain
consistent, without elements like `Build%20for%20fedora-35`.

The 'Total Success' task only ever executes when all dependencies are
successful.  When a non `[CI:DOCS]` build is successful, gather all
binary/release artifacts in a new task which depends on 'Total Success'.
This will provide a uniform name (`artifacts`) and URL for downstream
users to use.  For example:

https://api.cirrus-ci.com/v1/artifact/github/containers/podman/artifacts/binary.zip

or

https://api.cirrus-ci.com/v1/artifact/github/containers/podman/artifacts/binary/FILENAME

Where ***FILENAME*** is one of:

* `podman`
* `podman-remote`
* `rootlessport`
* `podman-release-386.tar.gz`
* `podman-release-amd64.tar.gz`
* `podman-release-arm64.tar.gz`
* `podman-release-arm.tar.gz`
* `podman-release-mips64le.tar.gz`
* `podman-release-mips64.tar.gz`
* `podman-release-mipsle.tar.gz`
* `podman-release-mips.tar.gz`
* `podman-release-ppc64le.tar.gz`
* `podman-release-s390x.tar.gz`
* `podman-remote-release-darwin_amd64.zip`
* `podman-remote-release-darwin_arm64.zip`
* `podman-remote-release-windows_amd64.zip`
* `podman-v4.0.0-dev.msi`
