The compiler flag `compileNonExportedClasses` allows the Angular compiler to
process classes which are not exported at the top level of a source file.
This is often used to allow for AOT compilation of test classes inside
`it()` test blocks, for example.
Previously, the compiler would identify exported classes by looking for an
`export` modifier on the class declaration itself. This works for the
trivial case, but fails for indirectly exported classes:
```typescript
// Component is declared unexported.
@Component({...})
class FooCmp {...}
// Indirect export of FooCmp
export {FooCmp};
```
This is not an immediate problem for most application builds, since the
default value for `compileNonExportedClasses` is `true` and therefore such
classes get compiled regardless.
However, in the Angular Language Service now, `compileNonExportedClasses` is
forcibly overridden to `false`. That's because the tsconfig used by the IDE
and Language Service is often far broader than the application build's
configuration, and pulls in test files that can contain unexported classes
not designed with AOT compilation in mind.
Therefore, the Language Service has trouble working with such structures.
In this commit, the `ReflectionHost` gains a new API for detecting whether a
class is exported. The implementation of this method now not only considers
the `export` modifier, but also scans the `ts.SourceFile` for indirect
exports like the example above. This ensures the above case will be
processed directly in the Language Service.
This new operation is cached using an expando symbol on the `ts.SourceFile`,
ensuring good performance even when scanning large source files with lots of
exports (e.g. a FESM file under `ngcc`).
Fixes#42184.

The documentation suggested that `@types/*` scoped packages would
automatically be recognized, however the CLI configures a project such
that the package has to be explicitly added to the TypeScript
configuration files.

We were linting against usages of `fdescribe` and `fit` by referencing the `no-jasmine-focus` rule which isn't installed, causing tslint to log the following:
```
Could not find implementations for the following rules specified in the configuration:
no-jasmine-focus
Try upgrading TSLint and/or ensuring that you have all necessary custom rules installed.
If TSLint was recently upgraded, you may have old rules configured which need to be cleaned

These changes switch to using the built-in `ban` rule.

This commit changes the `engines` rules in the root `package.json` as
well as the `package.json` used when working on docs example to also
accept Node.js versions greater than v14. This aligns them with
`aio/package.json` and allows using Node.js v15 and v16 (current) for
local development in the `angular/angular` repo.

Fixes#35373.
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.

This commit fixes some linting warning that were printed when running
`ng lint`. The warnings can be seen in the `lint` step of
[this CI job][1].
Most of the warnings were related to the deprecation of passing context
to Jasmine matchers in favor of using the [withContext()][2] matcher
(introduced in Jasmine v3.3.0).

Previously the docs were very minimalistic. The most important thing missing from the docs
was that people should primarily use higher level APIs instead of using ROUTES directly.
It would be nice to holistically overhaul more of the router API docs, but that's out of
scope of this change.
