Before #41162, angular.io was broken on IE 11 due to missing a polyfill
for an API (`Reflect.construct()`) needed by the Custom Elements ES5
shim. #41162 tried to fix this by loading the necessary polyfill
(`es.reflect.construct.js`) on browsers that do not support ES2015
modules (including IE 11).
It turns out that the fix in #41162 was itself broken, because the
`es.reflect.consruct.js` script (included directly in the page via a
`<script>` tag) was in CommonJS format (which cannot run in the browser
as is). By chance, this still allowed browsers that supported neither
Custom Elements nor ES2015 modules (such as IE 11) to work correctly as
a side-effect of loading the `@webcomponents/custom-elements` polyfill
after the Custom Elements ES5 shim (`native-shim.js`). However, on the
few browsers that natively support Custom Elements but not ES2015
modules, angular.io would still be broken.
This commit correctly fixes angular.io on all browsers by properly
bundling the polyfills and transpiling to ES5.
Implementation-wise, we use [esbuild][1] for bundling the polyfills (and
converting from CommonJS to a browser-compatible, IIFE-based format) and
[swc][2] for downleveling the code to ES5 (since `esbuild` only supports
ES2015+).

This commit updates the Angular framework, Angular CDK/Material and
Angular CLI to latest stable versions (11.2.3, 11.2.2 and 11.2.2
respectively).
This update also fixes a Lighthouse audit fail due to
`@angular/core@11.0.0` being identified as vulnerable to XSS:
https://snyk.io/vuln/SNYK-JS-ANGULARCORE-1070902
Regarding the payload size increases, they are mostly attributed to
Angular Material:
- Before this commit: 448461 B
- After framework update: 448554 B ( +93 B)
- After Material update: 449292 B (+738 B)
- After CLI update: 449310 B ( +18 B)

In this version, we no longer need our custom logic to skip certain
HTTPS related audits on localhost, since Lighthouse will treat it as a
secure context (similar to how browsers do).

Previously, the event dates displayed on the angular.io "Events" page
(`/events`) was off by one day on timezones with a negative offset from
UTC. See
https://github.com/angular/angular/pull/41050#issuecomment-788958888.
This commit fixes it by using the `getUTC*` methods of the `Date` object
to extract the date info, which are not affected by the user's timezone.

This commit updates `lighthouse` to version 7.0.0.
It also adds a `width` attribute to the `code-icon.svg` image on the
homepage, which was pointed out as missing in the Lighthouse report.
(Explicit `width`/`height` attributes on images help reduce the
[layout shift][1] of the page.)

This commit updates `@angular/*` and `@angular/cli` (and related

latest CLI. (See [here][1] for a diff between a v10.1.3 and a
v11.0.0-rc.2 CLI app.)

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.

This tool can be run from anywhere in the aio folder as:
```sh
yarn create-example <example-name>
```
It will create some basic scaffold files to get the example started.
After creation the developer should then use `yarn boilerplate:add`
or similar to ensure that the example can be run and tested.
You can optionally provide an absolute path to a pre-existing CLI
project and it will copy over appropriate files (ignoring boilerplate)
to the newly created example.
```sh
yarn create-example <example-name> /path/to/other/cli/project
```

When working on the docs, it is helpful to run a local instance of the
angular.io app and run scripts that watch both the docs contents and the
app build artifacts to automatically update the running instance on
changes. Typically, this is achieved via the `start` and `docs-watch`
npm scripts. As a convenience, one can run the `serve-and-sync` script,
which runs both in one terminal.
Previously, it was not possible to pass arguments to `ng nerve` (which
is what the `start` script runs under the hood) when running it via
`serve-and-sync`.
This commit adds support for passing any arguments passed to
`serve-and-sync` through to the `start` script. This can be useful for
things like specifying a custom host or port.

Bump Chrome to the next stable release (84.0.4147) by following the
instructions in dev-infra/browsers/README.md.
With Chrome 86 about to be released as stable, the current local version
(Chrome 83) is starting to lag behind. It also contains a bug that
blocks Angular unit and integration tests from using Trusted Types.
