Issue number: N/A

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

The `angular` directory sits at the root of the project instead of in
`packages` with all the other JS Framework integrations. This does not
cause any functional issues with Ionic, but it is confusing since
integrations are not in a consistent place.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Moves the `angular` directory to `packages/angular`

Note: Most files should remain unchanged. The only files I changed are
the files that had direct paths to the old `angular` directory:

1. Removes the `angular` path in `lerna.json`. This is now covered by
`packages/*`
2. Updated the angular file path in `.gitignore`
3. Updates the path to the angular package in `stencil.config.ts` for
the Angular Output Targets
4. Updates some of Angular's sync scripts to correctly get the core
stylesheets as well as the core package.
5. Updates the test app sync script to correctly sync core and
angular-server

~I'm not entirely sure why GitHub thinks
https://github.com/ionic-team/ionic-framework/pull/27719/files#diff-f5bba7e7c7c75426e2b9c89868310cb03890493b4efe0252adf8d12cc8398962
is a new file since it exists in `main` here:
1f06be4a31/angular/test/base/scripts/build-ionic.sh~
