Since #39853, it is possible to deploy to multiple Firebase sites from a
single branch. In order to deploy to a site, we need to associate an
alias (`aio`) with a site. This is done via the `firebase target:apply`
command. However, when the command is called multiple times, it
associates the alias with many sites, which subsequently fails during
deployment ([example failure][1]), since the `firebase deploy` command
does not know what site to deploy to.
This commit fixes the deployment script by ensuring that any previous
association with the `aio` alias is cleared (via the
`firebase target:clear` command) before associating it with a new site.

Currently there is an issue with redirecting `rc.angular.io` to
`angular.io` when there is no active RC. If a user has visited
`rc.angular.io` before and has a ServiceWorker registered for that
subdomain, they will never "see" the redirect to `angular.io`.
This commit fixes the problem by doing an additional deployment from the
stable branch to the `rc-angular-io-site` Firebase site when there is no
active RC. This additional deployment will ensure that:
1. Users will be temporarily redirected from `rc.angular.io` to
`angular.io`.
2. Users with a registered ServiceWorker (who don't see the redirect)
will have their ServiceWorker unregistered on the next visit.
3. The content on both sites is identical.
See #39760 for more details on the problem and the solution.
NOTE:
As mentioned in #39760, for this fix to take affect, we need to remove
the redirect from `rc.angular.io` to `angular.io` in the Firebase
console for site `rc-angular-io-site`.

Previously, a branch would be deployed as `archive` even if it had a
major version that was equal/higher than that of the stable branch (as
long as it was not the RC branch - i.e. not the most recent minor
branch). For example, with `11.0.x` as the stable branch and `12.0.x`
as the RC branch, `11.1.x` would be deployed as archive.
Theoretically, we should never find ourselves in such a situation.
Typically, there will only be at most one minor branch most recent than
the stable one (and that branch will be the RC branch). However, it
is possible under unusual circumstances.
This commit adds additional checks to guard against this problem. It
also refactors the code in preparation of fixing an issue with
`rc.angular.io` redirects in the presence of a ServiceWorker, which will
require identifying whether there is an active RC version or not.
See #39760 for more details.

Previously, the `deploy-to-firebase.js` script would only perform one
deployment operation on each run.
This commit adds support for performing multiple deployment operations.

Previously, the `deploy()` function in `deploy-to-firebase.js` would
also perform other operations (beyond deploying), such as building the
app, checking the generated payload size, testing the PWA score of the
deployed app.
This commit decouples these operations, so that deploying can be
performed independently.

In #39470, the `deploy-to-firebase.sh` script (used to deploy AIO to
Firebase when building an upstream branch), was replaced by an
equivalent JS script. In this new `deploy-to-firebase.js` script, we
were overly aggressive with suppressing command output, which made it
hard to investigate failures ([example failing CI job][1]).
This commit updates the `deploy-to-firebase.js` script to capture
command output as usual in the CI job logs. This makes the output
similar to the one generated by the old [deploy-to-firebase.sh][2]
script ([example CI logs][3]).
One concern with capturing command output is having the value of a
secret environment variables leaked in the logs. This is not the case
here, since:
1. The secret env vars are not printed from the commands that use them.
2. CircleCI will [mask the values of secret env vars][4] in the output.
As an extra precaution (although not strictly necessary), we run `yarn`
with the `--silent` option, which avoid echoing the executed yarn
commands.

The commit updates the AIO deployment script to also print the commit
SHA. This makes it easier to check whether a version has been
successfully deployed, by comparing the commit SHA from the CI job with
the SHA in the version string in the footer of the AIO app.

Previously, the documentation for each major Angular version was hosted
on each own Firebase project. This required creating a new project for
each major release and increased the administrative/maintenance cost.
Now that Firebase supports hosting [multiple websites][1] as part of the
same project, we are switching to deploying all major versions to sites
created on `angular-io` project.
This is part of the work needed to prepare angular.io for our
[new versioning/branching process][2] (also tracked in #39366).

This commit breaks up the code in `deploy-to-firebase.js` script, that
we use for deploying angular.io to production, to smaller functions
(instead of a monolithic block). This makes the script easier to
maintain and also makes testing individual operations easier.
The commit also updates the `deploy-to-firebase.spec.js` spec file to
take advantage of the standalone functions to speed up testing by
calling the corresponding function instead of having to spawn a new
process and run the `deploy-to-firebase.js` script with the `--dry-run`
flag.
NOTE: Before updating the tests, I verified that the updated
`deploy-to-firebase.js` script passed the old tests.

Previously, the `deploy-to-firebase.js` script and the accompanying
`deploy-to-firebase.spec.js` spec file were using the `origin` remote
alias in certain commands. This works fine on CI, where `origin` points
to the `angular/angular` GitHub repo, but might not work locally.
This commit ensures that the correct remote is used by explicitly
specifying it by the URL, thus ensuring that the tests will behave
identically on CI and locally.

This commit switches the `deploy-to-firebase.sh` script, that we use for
deploying angular.io to production, from Bash to JavaScript. This makes
the script easier to maintain.
For the same reasons, it also switches the `deploy-to-firebase.test.sh`
script, that we use for testing the `deploy-to-firebase` script, from
Bash to JavaScript (using jasmine as the test runner).
Finally, this commit also updates ShellJS to the latest version to get
better error messages (including the actual error) when `exec()` fails.
NOTE: Before switching the test script to JS, I verified that the new
`deploy-to-firebase.js` script passed the tests with the old
`deploy-to-firebase.test.sh` script.
