Previously, redirects had to be configured in both the Firebase config
(`firebase.json`) and the ServiceWorker config (`ngsw-config.json`).
This made it challenging to correctly configure redirects, since one had
to understand the different formats of the two configs, and was also
prone to getting out-of-sync configs.
This commit simplifies the process of adding redirects by removing the
need to update the ServiceWorker config (`ngsw-config.json`) and keep it
in sync with the Firebase config (`firebase.json`). Instead the
ServiceWorker `navigationUrls` are automatically generated from the list
of redirects in the Firebase config.
NOTE:
Currently, the automatic generation only supports the limited set of
patterns that are necessary to translate the existing redirects. It can
be made more sophisticated in the future, should the need arise.

Previously, styling of `<code>` elements utilized the `:not()` CSS
pseudo-class with multiple selectors (`:not(h1, h2, ...)`). It turns out
that older browsers (such as IE11) do not support multiple selectors in
a single `:not()` instance.
(See [MDN][1] and [CanIUse][2] for more info.)

This change seems to trigger some kind of bug in LightHouse that causes

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.

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.

In the process of updating the scripts I rediscovered a bug in the deploy-to-firebase.sh script that
incorrect compared two numbers as strings. This previously worked correctly because we were comparing
single digit numbers. With the release of v10, we now compare 9 > 10 which behaves differently for
strings and numbers. The bug was fixed by switching to an arithmetic comparison of the two variables.

rebase, but found my version to be a bit cleaner, so I kept it.

The angular.io production deployment script (`deploy-to-firebase.sh`)
compares the major version corresponding to the current branch (e.g.
`8` for branch `8.1.x`) against the major stable version (e.g. `9` if
the current stable version is `9.1.0`). It then uses the result of that
comparison to determine whether the current branch corresponds to a
newer version than stable (i.e. an RC version) and thus should not be
deployed or to an older version and thus may need to be deployed to an
archive vX.angular.io project.
Previously, the script was using string comparison (`<`) to compare the
two major versions. This could produce incorrect results for an RC major
version that is numerically greater than the stable but
lexicographically smaller. For example, 10 vs 9 (10 is numerically
greater but lexicographically smaller than 9).

production: https://circleci.com/gh/angular/angular/726414

Currently destroy hooks are stored in memory as `[1, hook, 5, hook]` where
the numbers represent the index at which to find the context and `hook` is
the function to be invoked. This breaks down for `multi` providers,
because the value at the index will be an array of providers, resulting in
the hook being invoked with an array of all the multi provider values,
rather than the provider that was destroyed. In ViewEngine `ngOnDestroy`
wasn't being called for `multi` providers at all.
These changes fix the issue by changing the structure of the destroy hooks to `[1, hook, 5, [0, hook, 3, hook]]` where the indexes inside the inner array point to the provider inside of the multi provider array. Note that this is slightly different from the original design which called for the structure to be `[1, hook, 5, [hook, hook]`, because in the process of implementing it, I realized that we wouldn't get passing the correct context if only some of the `multi` providers have `ngOnDestroy` and others don't.
I've run the newly-added `view_destroy_hooks` benchmark against these changes and compared it to master. The difference seems to be insignificant (between 1% and 2% slower).
