The change in e041ac6f0d
to support sending unlocker process output to the main ngcc
console output prevents messages require that the main process
relinquishes the event-loop to allow the `stdout.on()` handler to
run. This results in none of the messages being written when ngcc
is run in `--no-async` mode, and some messages failing to be
written if the main process is killed (e.g. ctrl-C).
It appears that the problem with Windows and detached processes
is known - see https://github.com/nodejs/node/issues/3596#issuecomment-250890218.
But in the meantime, this commit is a workaround, where non-Windows
`inherit` the main process `stdout` while on Windows it reverts
to the async handler approach, which is better than nothing.

This rewrite changes headings to focus on user tasks rather than features,
verifies that content is up-to-date and complete, removes colloquial phrases,
adds prerequisites, and expands on a task-based section in the beginning
(a quick reference).

Prior to this commit, the unknown property check was unnecessarily invoked for AOT-compiled components (for these components, the check happens at compile time). This commit updates the code to avoid unknown property verification for AOT-compiled components by checking whether schemas information is present (as a way to detect whether this is JIT or AOT compiled component).
Resolves#35945.

Prior to this change, there was a problem while matching template attributes, which mistakenly took i18n attributes (that might be present in attrs array after template ones) into account. This commit updates the logic to avoid template attribute matching logic from entering the i18n section and as a result this also allows generating proper i18n attributes sections instead of keeping these attribute in plain form (with their values) in attribute arrays.

In the past, server-side rendered apps needed to convert URLs used in
API requests to absolute when rendering on the server. Originally, this
was handled in the `universal` guide and corresponding example app by
modifying the `HeroService` to use `APP_BASE_HREF` to derive the
absolute URL.
In #28956, the guide was updated to show an improved method: Specifying
an `HttpInterceptor` that took care of converting the URLs to absolute.
That interceptor was only provided when rendering the app on the server.
By mistake, the corresponding example app was not updated along with the
guide.
Since `@nguniversal/*` v7.1.0, it is no longer necessary to convert the
URLs to absolute inside the app. This is handled in the `@nguniversal`
libs (see angular/universal#897).
This commit updates the example app to remove unnecessary code and
modifies the guide to mention the issue with absolute URLs, but explain
that developers only need to worry about it when not using one of the
`@nguniversal/*-engine` packages.

Previously, there were no tests for the `universal` docs example. This
meant that the project was not tested at all (not even ensuring that it
can be built successfully).
This commit adds e2e tests for the `universal` example (ported from
`toh-pt6` and cleaned up) and also verifies that the project can be
built successfully (including the server).

Previously, building the `universal` example failed with:
```

node_modules/@types/express/index.d.ts(90,64): error TS2694: Namespace '".../@types/express-serve-static-core/index"' has no exported member 'ParamsDictionary'.

This commit fixes the error by upgrading
`@types/express-serve-static-core` to a newer version.

As mentioned in the `universal` guide, the `toh-pt6` examples is the
starting poitn for the `universal` example. However, the two examples
had become out-of-sync, because some fixes/changes were made to the
Tour-of-Heroes examples.
This commit ports these changes to the `universal` example.

Previously, the `package.json` template used in the ZIP archive of the
`universal` example that we offer for download missed the `build` npm
script.
This commit updates the template for the `universal` docs example to
include the `build` npm script.
NOTE:
The `build` npm script is already included in
`aio/tools/examples/shared/boilerplate/universal/package.json`, but it
was removed by the example zipper.

In certain use-cases it's useful to have an ability to use empty strings as translations. Currently Ivy fails at runtime if empty string is used as a translation, since some parts of internal data structures are not created properly. This commit updates runtime i18n logic to handle empty translations and avoid unnecessary extra processing for such cases.
Fixes#36476.

When formatting a time with the `b` or `B` format codes, the rendered
string was not correctly handling day periods that spanned midnight.
Instead the logic was falling back to the default case of `AM`.
Now the logic has been updated so that it matches times that are within
a day period that spans midnight, so it will now render the correct
output, such as `at night` in the case of English.
Applications that are using either `formatDate()` or `DatePipe` and any
of the `b` or `B` format codes will be affected by this change.

On Windows, the output of a detached process (such as the unlocker
process used by `LockFileWithChildProcess`) is not shown in the parent
process' stdout.
This commit addresses this by piping the spawned process' stdin/stdout
and manually writing to the parent process' stdout.

The current ngcc lock-file strategy spawns a new process in order to
capture a potential `SIGINT` and remove the lock-file. For more
information see #35861.
Previously, this unlocker process was spawned as soon as the `LockFile`
was instantiated in order to have it available as soon as possible
(given that spawning a process is an asynchronous operation). Since the
`LockFile` was instantiated and passed to the `Executor`, this meant
that an unlocker process was spawned for each cluster worker, when
running ngcc in parallel mode. These processes were not needed, since
the `LockFile` was not used in cluster workers, but we still had to pay
the overhead of each process' own memory and V8 instance.
(NOTE: This overhead was small compared to the memory consumed by ngcc's
normal operations, but still unnecessary.)
This commit avoids the extra processes by only spawning an unlocker
process when running on the cluster master process and not on worker
processes.

For some reason (possibly related to async/await promises)
the ngcc process is not exiting when spawned from the CLI
when there has been an error (such as when it timesout waiting
for a lockfile to become free).
Calling `process.exit()` directly fixes this.

With the large scale refactoring of the repo to the new version of clang-format, some import orders were changed.
Specifically the imports found in this range.
The file previously read:
import {TestBed} from './test_bed';
import {ComponentFixtureAutoDetect, ComponentFixtureNoNgZone, TestBedStatic, TestComponentRenderer, TestModuleMetadata} from './test_bed_common';
import {R3TestBedCompiler} from './r3_test_bed_compiler';
and now reads:
import {R3TestBedCompiler} from './r3_test_bed_compiler';
import {TestBed} from './test_bed';
import {ComponentFixtureAutoDetect, ComponentFixtureNoNgZone, TestBedStatic, TestComponentRenderer, TestModuleMetadata} from './test_bed_common';
This change in order cause the circular dependency to be entered earlier and changed the golden file for our circular deps discovery.

Updates the $locationShim to receive the most recent Location change
made, even if it happened before initialize() is called. This is
important when AngularJS bootstrapping is deferred and there is a delay
between when $locationShim is constructed and when it is initialized.
With this change, the $locationShim will correctly reflect any redirects
that occurred between construction and initialization.

The undecorated-classes-with-decorated-fields migration relies on
the type checker to resolve base classes of individual classes.
It could happen that resolved base classes have no value declaration.
e.g. if they are declared through an interface in the default types.
Currently the migration will throw in such situations because it assumes
that `ts.Symbol#valueDeclaration` is always present. This is not the
case, but we don't get good type-checking here due to a bug in the
TypeScript types. See:
https://github.com/microsoft/TypeScript/issues/24706.
Fixes#36522.

Previously, when we needed to detect whether a file is external to a
package, we only checked whether the relative path to the file from the
package's root started with `..`. This would detect external imports
when the packages were siblings (e.g. peer dependencies or hoisted to
the top of `node_modules/` by the package manager), but would fail to
detect imports from packages located in nested `node_modules/` as
external. For example, importing `node_modules/foo/node_modules/bar`
from a file in `node_modules/foo/` would be considered internal to the
`foo` package.
This could result in processing/analyzing more files than necessary.
More importantly it could lead to errors due to trying to analyze
non-Angular packages that were direct dependencies of Angular packages.
This commit fixes it by also verifying that the relative path to a file
does not start with `node_modules/`.

Previously, the `elements` docs example only worked in browsers that
natively supported Custom Elements and ES2015 modules. Furthermore, it
didn't work on StackBlitz, because StackBlitz ignores the specified
`target` in `tsconfig.json` and uses the UMD bundles (i.e. ES5 code)
even on browsers that do support ES2015.
(NOTE: In the past, this was not a problem, because we explicitly did
not provide a StackBlitz example. This has changed in #36067.)
This commit ensures the example works on all browsers and also on
StackBlitz by providing the necessary Custom Elements polyfills.
