Bumps the minimum required TypeScript version to 4.4.2 and removes the integration tests for 4.1, 4.2 and 4.3.
BREAKING CHANGE:
TypeScript versions older than 4.4.2 are no longer supported.

Update the AIO scripts that use Lighthouse (i.e. `audit-web-app.js` and
`test-aio-a11y.js`) to ES modules. This allows consuming
`lighthouse/lighthouse-cli` [v8.5.0+][1], which also switched to ES
modules.
NOTE:
Switching the `test-aio-a11y.js` script to ES modules is not strictly
necessary, since it invokes `audit-web-app.mjs` via a shell command, but
it was done for consistency.

The CLI has been updated with various changes to support for ESM package
output of the framework. This commit updates to a next version of the
CLI v13 that contains these necessary changes, allowing us to test/validate
our package changes through integration tests or AIO examples.
This update also contains a fix for the adjust enum babel optimization
that broke with the latest rollup version.

Adds support for TypeScript 4.4. High-level overview of the changes made in this PR:
* Bumps the various packages to `typescript@4.4.2` and `tslib@2.3.0`.
* The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere.
* TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly.
* TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624.
* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.
* Some browser types were updated which meant that I had to resolve some trivial type errors.
* The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it.

tsec is a TypeScript compiler wrapper for restricting use of
security-sensitive DOM APIs, in particular those that could lead to XSS
or Trusted Types violations. Add it as a linter to aio to prevent future
Trusted Types regressions on angular.io.
Also introduces security_exemptions.json, which lists the known,
security-reviewed tsec security violations. New entries can only be
added to this file after a security review, in particular making sure
that the corresponding code does not cause XSS vulnerabilities or
Trusted Types violations.
PR Close#42800
Also introduce a dependency on the Trusted Types type definitions and a
Trusted Types polyfill, safevalues. Create a security module for common,
security-reviewed transformations into Trusted Types.

migrate aio to eslint as tslint has been deprecated, the migration is restricted to the aio app and
its e2e tests and does not include the other tools, for such reason both tslint and codelyzer have not
been removed (to be done in a next PR)
some minor tweaks needed to be applied to the code so that it would adhere to the new ESLinting behaviour
most TSLint rules have been substituted with their ESLint equivalent, with some exceptions:
* [whitespace] does not have an ESLint equivalent (suggested to be handled by prettier)
* [import-spacing] does not have an ESLint equivalent (suggested to be handled by prettier)
* [ban] replaced with [no-restricted-syntax] as there is no (official/included) ESLint equivalent
some rules have minor different behaviours compared to their TSLint counterparts:
* @typescript-eslint/naming-convention:
- typescript-eslint does not enforce uppercase for const only.
* @typescript-eslint/no-unused-expressions:
- The TSLint optional config "allow-new" is the default ESLint behavior and will no longer be ignored.
* arrow-body-style:
- ESLint will throw an error if the function body is multiline yet has a one-line return on it.
* eqeqeq:
- Option "smart" allows for comparing two literal values, evaluating the value of typeof and null comparisons.
* no-console:
- Custom console methods, if they exist, will no longer be allowed.
* no-invalid-this:
- Functions in methods will no longer be ignored.
* no-underscore-dangle:
- Leading and trailing underscores (_) on identifiers will now be ignored.
* prefer-arrow/prefer-arrow-functions:
- ESLint does not support allowing standalone function declarations.
- ESLint does not support allowing named functions defined with the function keyword.
* space-before-function-paren:
- Option "constructor" is not supported by ESLint.
- Option "method" is not supported by ESLint.
additional notes:
* the current typescript version used by the aio app is 4.3.5, which is not supported by typescript-eslint (the supported
versions are >=3.3.1 and <4.3.0). this causes a warning message to appear during linting, this issue should
likely/hopefully disappear in the future as typescript-eslint catches up
* The new "no-console" rule is not completely equivalent to what we had prior the migration, this is because TSLint's "no-console"
rule let you specify the methods you did not want to allow, whilst ESLint's "no-console" lets you specify the methods that you do
want to allow, so and in order not to have a very long list of methods in the ESLint rule it's been decided for the time being
to simply only allow the "log", "warn" and "error" methods
* 4 dependencies have been added as they have been considered necessary (see: https://github.com/angular/angular/pull/42820#discussion_r669978232)
extra:
* the migration has been performed by following: https://github.com/angular-eslint/angular-eslint#migrating-an-angular-cli-project-from-codelyzer-and-tslin
* more on typescript-eslint at: https://github.com/typescript-eslint/typescript-eslint

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.

This commit aligns the angular.io config files more closely to how a
newly generated CLI v12 app would look like. This helps validate the
setup and makes it easier to apply new chages in the future (by
preventing the angular.io layout from deviating too much from the
default new app layout).

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.
