Switches the repository to TypeScript 4.3 and the latest
version of tslib. This involves updating the peer dependency
ranges on `typescript` for the compiler CLI and for the Bazel
package. Tests for new TypeScript features have been added to
ensure compatibility with Angular's ngtsc compiler.

Previously, the critical CSS inlining optimization (which is turned on
by default in CLI v12+) was causing a Flash Of Unstyled Content (FOUC).
This was caused by the combination of the following facts:
- The way CSS inlining is implemented in the CLI makes loading the full
styles asynchronous and non-render-blocking (so the app can bootstrap
before the styles are fully downloaded).
- Angular.io does not employ the [app shell][1] pattern in order to
render pages at build time, resulting in very minimal CSS rules being
recognized as critical (for the purpose of inlining).
This commit fixes the FOUC by disabling the critical CSS inlining, while
we consider a better way to approach this (in order to be able to rip
the benefits of inlining without the FOUC).

As previously discussed in pull/31070 and issues/30486, this would be useful because it is often desirable to apply styles to fields that are both `ng-invalid` and `ng-pristine` after the first attempt at form submission, but Angular does not provide any simple way to do this (although evidently Angularjs did). This will now be possible with a descendant selector such as `.ng-submitted .ng-invalid`.
In this implementation, the directive that sets control status classes on forms and formGroups has its set of statuses widened to include `ng-submitted`. Then, in the event that `is('submitted')` is invoked, the `submitted` property of the control container is returned iff it exists. This is preferred over checking whether the container is a `Form` or `FormGroup` directly to avoid reflecting on those classes.
Closes#30486.

Cleans up AIO's Sass files by:
* Switching them all over to the `@use`-based API from Angular Material.
* Removing the import of the Material theming API in a bunch of places that weren't using it.
* Migrating the new usages of Sass utility functions to the new syntax (e.g. `map.get` vs `map-get`).
* Fixing a few files that were using 4 spaces for indentation instead of 2.

This changes the example from "run an arbitrary process" to "copy a file". This should make it a bit easier to follow, require less background knowledge to understand, and not use any platform-specific commands that won't work for Windows users.
The most glaring issue with this change is that this doc does not explictly specify how to build and run a builder. I've updated some of the files to hint at this a bit more (such as the `"implementation": "./dist/my-builder.js"`), but another pass is required to figure out the best way to compile a builder and how we want to structure this example to best communicate that.

A couple important things to note about the behavior:
* The component is destroyed, meaning that all of its members will be destroyed as well, including any subscriptions to the route params
* This _does not_ mean that any `finalize` operators or `complete` on the subscription is called. This only happens if the source completes or you unsubscribe from the subscription. The documentation doesn't state that the `Router` will do this, though I can still understand why the behavior is confusing.
You can play around with these scenarios here:
https://stackblitz.com/edit/rxjs-hmpizx
* `complete` the source without unsubscribe: `next`, `complete` and `finalize` are all called, even when `complete` is called before the `next` from the `delay`
* `unsubscribe` from subscription without `complete` on the source: `finalize` happens, but the `complete` of the subscription does not, and neither does `next`
So even if the `Router` were to call `complete` on all of the `Observables` on an `ActivatedRoute`, you would see that any subscriptions with a `delay` operator would still get called.

The latest SW app version knows that `/devtools` should be redirected to
`/guide/devtools`. However, if a user has an older app version installed
(and until the SW downloads the latest version) they will get a 404 when
navigating to `/devtools`.
The reason is that the SW will see `/devtools` as a regular navigation
URL and serve `index.html` instead. The Angular app will then try to get
the content for `/devtools` by fetching `/generated/docs/devtools.json`
(which does not exist).
This commit fixes the issue by redirecting
`/generated/docs/devtools.json` to
`/geenrated/docs/guide/devtools.json`. When a user visits `/devtools`
for the first time, they will still be able to see the guide content
(while the SW updates in the background). On subsequent visits (once the
SW has downloaded the latest app version), they will be redirected to
`/guide/devtools`).
At a later time, once we are confident that the majority of users will
have updated to a newer app version, we can remove this temporary
redirect.

This fixes an issue in part 5 of the Tour of Heroes tutorial on
angular.io. At the end of the `Add RouterOutlet` section, the reader navigates to
`"/heroes"`. The next section, `Add a navigation link`, instructs the user to click ona link on the dashboard page to navigate to the heroes page. This is problematic because the previous section instructed the reader to navigate to the heroes page, not the dashboard. It assumes, the reader is on the dashboard page.
Fixes issue by instructing the reader to navigate back to the dashboard
after navigating to `"/heroes"` in the `Add RouterOutlet` section.
