Follow-up to #30993 where we build all Angular packages with
the TypeScript `--strict` flag. The flag improves overall code
health and also helps us catch issues easier.

Historically, we've cleaned Ivy commits out of the CHANGELOG because
Ivy was not available except as a preview. Given that Ivy will soon
be the default in 9.0.0, it no longer makes sense to remove the Ivy
commits from the log. This changes the gulp changelog task so that
Ivy commits are included by default.

Previously, `validate-commit-message` would treat `fixup! `-prefixed
commits like this:
- It would strip the `fixup! ` prefix.
- It would validate the rest of the commit message header as any other
commit.
However, fixup commits are special in that they need to exactly match an
earlier commit message header (sans the `fixup! ` prefix) in order for
git to treat them correctly. Otherwise, they will not be squashed into
the original commits and will be merged as is. Fixup commits can end up
not matching their original commit for several reasons (e.g. accidental
typo, changing the original commit message, etc.).
This commit prevents invalid fixup commits to pass validation by
ensuring that they match an earlier (unmerged) commit (i.e. a commit
between the current HEAD and the BASE commit).
NOTE: This new behavior is currently not activated in the pre-commit git
hook, that is used to validate commit messages (because the
preceding, unmerged commits are not available there). It _is_
activated in `gulp validate-commit-message`, which is run as part
of the `lint` job on CI and thus will detect invalid commits,
before their getting merged.
PR Close#32023
While `fixup! ` is fine, `squash! ` means that the commit message needs
tweaking, which cannot be done automatically during merging (i.e. it
should be done by the PR author).
Previously, `validate-commit-message` would always allow
`squash! `-prefixed commits, which would cause problems during merging.
This commit changes `validate-commit-message` to make it configurable
whether such commits are allowed and configures the
`gulp validate-commit-message` task, which is run as part of the `lint`
job on CI, to not allow them.
NOTE: This new check is disabled in the pre-commit git hook that is used
to validate commit messages, because these commits might still be
useful during development.

There has been a regression where enabling rollup treeshaking causes errors during runtime because it will drop const access which will always evaluate to true or false. However, such `const` in `@angular/core` cannot be dropped because their value is changed when NGCC is run on `@angular/core`

```
load(path) {
/** @type {?} */
const legacyOfflineMode = !ivyEnabled && this._compiler instanceof Compiler;
return legacyOfflineMode ? this.loadFactory(path) : this.loadAndCompile(path);

```
From the above we can see that `ivyEnabled ` is being treeshaken away when generating the FESM bundle which is causing runtime errors such as `Cannot find module './lazy/lazy.module.ngfactory'` since in Ivy we will always load the factories.

Similar to interpolation, we do not want to completely remove whitespace
nodes that are siblings of an expansion.
For example, the following template
```html
<div>
<strong>items left<strong> {count, plural, =1 {item} other {items}}
</div>
```
was being collapsed to
```html
<div><strong>items left<strong>{count, plural, =1 {item} other {items}}</div>
```
which results in the text looking like
```
items left4
```
instead it should be collapsed to
```html
<div><strong>items left<strong> {count, plural, =1 {item} other {items}}</div>
```
which results in the text looking like
```
items left 4
```

In `BrowserModule` the value of `LOCALE_ID` is defined in the `APPLICATION_MODULE_PROVIDERS` after `APP_INITIALIZER` has run.
This PR ensures that `LOCALE_ID` is also set for ivy at the same moment which allows the application to fetch the locale from a backend (for example).

Examples for testing are designed specifically to run in StackBlitz and
are not regular cli projects (e.g. their `main.ts` files may load and run
tests instead of bootstrapping an app). They are not intended to be
downloaded and built/run locally using the cli.
In order to avoid confusing users, this commit removes the download links
from the guide. If desired, the projects can still be exported locally
via StackBlitz's UI.

The `setup-local` npm script uses `NgPackagesInstaller` to replace the
Angular packages with the locally built ones. Previously, it would (a)
assume that the packages were built and (b) it would do anything if the
currently installed versions already correspond to locally built
packages (even if not the latest version).
This could lead to all sorts of errors, such as:
- Confusing error messages, `dist/packages-dist/` was missing.
- Using outdated build artifacts from `dist/packages-dist/` without a
warning.
- Not installing the latest locally built packages, because the ones
installed already corresponded to locally built (but older) ones.
This commit fixes these issues by ensuring that:
- The local packages are always built before being used by
`NgPackagesInstaller`.
- The local packages are installed, even if the ones install already
correspond to local packages.
NOTE: Special `*-ci` scripts are introduced (for use on CI) that skip
building the local packages, since that step would have been taken
care of (in a more efficient way) in a previous CI step.
PR Close#31985
Previously, when `NgPackagesInstaller` needed to install the local
Angular packages to a project, it assumed the `dist/packages-dist/`
would exist and contain up-to-date built packages. I.e. it was up to the
user to have built the packages first (by running the appropriate
script).
However, many people not familiar with the `aio/` infrastructure assumed
that `yarn build-local` or `yarn build-with-ivy` would take care of all
the necessary steps.
To avoid getting confusing errors (or worse yet, using outdated local
packages), `NgPackagesInstaller` now has an option to build the packages
before using them.
One caveat is that the build script does not currently work on Windows,
so a warning is printed instead, letting the user know they need to
(somehow) take care of it themselves.
NOTE 1: Since the build script is using bazel, running it should not be
expensive if the directory is up-to-date (i.e. no changes have
been made to source code after the last build).
NOTE 2: This commit adds support for `--build-packages`, but does not
change the default behavior (not building the packages). It will
be turned on in a subsequent commit.
