Previously we only searched for package paths below the set of `basePaths`
that were computed from the `basePath` provided to ngcc and the set of
`pathMappings`.
In some scenarios, such as hoisted packages, the entry-point is not within
any of the `basePaths` identified above. For example:
```
project
packages
app
node_modules
app-lib (depends on lib1)
node_modules
lib1 (depends on lib2)
node_modules
lib2 (depends on lib3/entry-point)
lib3
entry-point
```
When CLI is compiling `app-lib` ngcc will be given
`project/packages/app/node_modules` as the `basePath.
If ngcc is asked to target `lib2`, the `targetPath` will be
`project/node_modules/lib1/node_modules/lib2`.
Since `lib2` depends upon `lib3/entry-point`, ngcc will need to compute
the package path for `project/node_modules/lib3/entry-point`.
Since `project/node_modules/lib3/entry-point` is not contained in the `basePath`
`project/packages/app/node_modules`, ngcc failed to compute the `packagePath`
correctly, instead assuming that it was the same as the entry-point path.
Now we also consider the nearest `node_modules` folder to the entry-point
path as an additional `basePath`. If one is found then we use the first
directory directly below that `node_modules` directory as the package path.
In the case of our example this extra `basePath` would be `project/node_modules`
which allows us to compute the `packagePath` of `project/node_modules/lib3`.

Prior to this commit, Ivy TestBed was accessing locale ID before `APP_INITIALIZER` functions were called. This execution order is not consistent with the app bootstrap logic in `application_ref.ts`. This commit updates Ivy TestBed execution order to call initializers first (since they might affect `LOCALE_ID` token value) and accessing and setting locale ID after that.

Currently the `ts-circular-deps` tool uses a hard-coded module resolver
that only works in the `angular/angular` repository.
If the tool is consumed in other repositories through the shared
dev-infra package, the module resolution won't work, and a few
resolvable imports (usually cross-entry-points) are accidentally
skipped. For each test, the resolution might differ, so tests can
now configure their module resolution in a configuration file.
Note that we intentionally don't rely on tsconfig's for module
resolution as parsing their mappings rather complicates the
circular dependency tool. Additionally, not every test has a
corresponding tsconfig file.
Also, hard-coding mappings to `@angular/*` while accepting a
path to the packages folder would work, but it would mean
that the circular deps tool is no longer self-contained. Rather,
and also for better flexibility, a custom resolver should be
specified.

In #35381, a new Protractor config file was introduced in docs examples,
`protractor-puppeteer.conf.js`, that was only supposed to be used on CI
and not be shipped with the ZIP archives provided for users to download
and experiment with the docs examples locally.
The logic to ignore the `protractor-puppeteer.conf.js` file was
incorrect, resulting in the file being retained in some examples (e.g.
[universal][1]). The problem was not immediately obvious, because most
examples explicitly specify all `**/*.js` files as ignored, but for
other examples the file was retained in the ZIP archive.
This commit fixes the logic to ensure the file is excluded from all docs
examples ZIP archives.

The `removeSystemJsConfig` and `type` properties (present in some
`zipper.json` files) are now obsolete and are not taken into account by
the example zipper:
- `removeSystemJsConfig` is no longer relevant since most examples have
been migrated to use the CLI.
- `type` is no longer relevant, because the project type is determined
based on the `projectType` property in `example-config.json` files.
This commit removes these properties from `zipper.json` files and
updates the `example-zipper` docs to not mention them.

Previously, some of the built-in ServiceWorker registration strategies,
namely `registerWithDelay:<timeout>` and `registerWhenStable:<timeout>`,
would register potentially long-running timeout, thus preventing the app
from stabilizing before the timeouts expired. This was especially
problematic for the `registerWhenStable:<timeout>` strategy, which waits
for the app to stabilize, because the strategy itself would prevent the
app from stabilizing and thus the ServiceWorker would always be
registered after the timeout.
This commit fixes this by subscribing to the registration strategy
observable outside the Angular zone, thus not affecting the app's
stabilization.
PR Close#35870
Previously, when using the default ServiceWorker registration strategy
Angular would wait indefinitely for the [app to stabilize][1], before
registering the ServiceWorker script. This could lead to a situation
where the ServiceWorker would never be registered when there was a
long-running task (such as an interval or recurring timeout).
Such tasks can often be started by a 3rd-party dependency (beyond the
developer's control or even without them realizing). In addition, this
situation is particularly hard to detect, because the ServiceWorker is
typically not used during development and on production builds a
previous ServiceWorker instance might be already active.
This commit fixes this by changing the default registration strategy
from `registerWhenStable` to `registerWhenStable:30000`, which will
ensure that the ServiceWorker will be registered after 30s at the
latest, even if the app has not stabilized by then.

This commit enhances the `registerWhenStable` registration strategy by
adding support for an optional `<timeout>` argument, which guarantees
that the ServiceWorker will be registered when the timeout expires, even
if the app has not stabilized yet.
For example, with `registerWhenStable:5000` the ServiceWorker will be
registered as soon as the app stabilizes or after 5 seconds if the app
has not stabilized by then.

`KeyValuePipe` currently accepts `null` values as well as `Map`s and a
few others. However, due to the way in which TS overloads work, a type
of `T|null` will not be accepted by `KeyValuePipe`'s signatures, even
though both `T` and `null` individually would be.
To make this work, each signature that accepts some type `T` has been
duplicated with a second one below it that accepts a `T|null` and
includes `null` in its return type.

Previously ngcc never preserved whitespaces but this is at odds
with how the ViewEngine compiler works. In ViewEngine, library
templates are recompiled with the current application's tsconfig
settings, which meant that whitespace preservation could be set
in the application tsconfig file.
This commit allows ngcc to use the `preserveWhitespaces` setting
from tsconfig when compiling library templates. One should be aware
that this disallows different projects with different tsconfig settings
to share the same node_modules folder, with regard to whitespace
preservation. But this is already the case in the current ngcc since
this configuration is hard coded right now.

This commit augments the `FactoryDef` declaration of Angular decorated
classes to contain information about the parameter decorators used in
the constructor. If no constructor is present, or none of the parameters
have any Angular decorators, then this will be represented using the
`null` type. Otherwise, a tuple type is used where the entry at index `i`
corresponds with parameter `i`. Each tuple entry can be one of two types:
1. If the associated parameter does not have any Angular decorators,
the tuple entry will be the `null` type.
2. Otherwise, a type literal is used that may declare at least one of
the following properties:
- "attribute": if `@Attribute` is present. The injected attribute's
name is used as string literal type, or the `unknown` type if the
attribute name is not a string literal.
- "self": if `@Self` is present, always of type `true`.
- "skipSelf": if `@SkipSelf` is present, always of type `true`.
- "host": if `@Host` is present, always of type `true`.
- "optional": if `@Optional` is present, always of type `true`.
A property is only present if the corresponding decorator is used.
Note that the `@Inject` decorator is currently not included, as it's
non-trivial to properly convert the token's value expression to a
type that is valid in a declaration file.
Additionally, the `ComponentDefWithMeta` declaration that is created for
Angular components has been extended to include all selectors on
`ng-content` elements within the component's template.
This additional metadata is useful for tooling such as the Angular
Language Service, as it provides the ability to offer suggestions for
directives/components defined in libraries. At the moment, such
tooling extracts the necessary information from the _metadata.json_
manifest file as generated by ngc, however this metadata representation
is being replaced by the information emitted into the declaration files.

Previously, when an input property was initially set to `undefined` it
would not be correctly recognized as a change (and trigger
`ngOnChanges()`).
This commit ensures that explicitly setting an input to `undefined` is
correctly handled the same as setting the property to any other value.
This aligns the behavior of Angular custom elements with that of the
corresponding components when used directly (not as custom elements).

This commit fixes this by ensuring `SimpleChange#firstChange` is set to
true on first change, regardless if the property was set before or after
instantiating the component. This alignthe behavior of Angular custom
elements with that of the corresponding components when used directly

When computing the dependencies between packages which are not in
node_modules, we may need to rely upon path-mappings to find the path
to the imported entry-point.
This commit allows ngcc to use the path-mappings from a tsconfig
file to find dependencies. By default any tsconfig.json file in the directory
above the `basePath` is loaded but it is possible to use a path to a
specific file by providing the `tsConfigPath` property to mainNgcc,
or to turn off loading any tsconfig file by setting `tsConfigPath` to `null`.
At the command line this is controlled via the `--tsconfig` option.
