Issue number: Internal

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

Adds the base architecture to add a new theme configuration to Ionic
Framework components.
- Components can now specify an additional stylesheet for the `ionic`
theme.
- Developers can specify the `theme` and `mode` independently to control
look and feel of a component.

Test infrastructure has been updated to add support for testing the
theme configuration with Playwright.
- Existing `themes` test configuration has been renamed to `palettes`

This PR is just the initial effort to decouple Ionic's architecture to
separate look and feel and allow our dev team to start introducing the
new component appearance to the UI. There will be additional changes
required to completely add support for the Ionic theme. These changes
are targeted against the `next` branch and are not expected to be used
in a production environment at this time.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

@ionic/angular

Ionic Angular specific building blocks on top of @ionic/core components.

Testing ng-add in ionic

  1. Pull the latest from main
  2. Build ionic/angular: npm run build
  3. Run npm link from ionic/angular/dist directory
  4. Create a blank angular project
ng new add-test
// Say yes to including the router, we need it
cd add-test
  1. To run schematics locally, we need the schematics-cli (once published, this will not be needed)
npm install @angular-devkit/schematics-cli
  1. Link @ionic/angular
npm link @ionic/angular
  1. Run the local copy of the ng-add schematic
$ npx schematics @ionic/angular:ng-add

You'll now be able to add ionic components to a vanilla Angular app setup.

Project Structure

common

This is where logic that is shared between lazy loaded and standalone components live. For example, the lazy loaded IonPopover and standalone IonPopover components extend from a base IonPopover implementation that exists in this directory.

Note: This directory exposes internal APIs and is only accessed in the standalone and src submodules. Ionic developers should never import directly from @ionic/angular/common. Instead, they should import from @ionic/angular or @ionic/angular/standalone.

standalone

This is where the standalone component implementations live. It was added as a separate entry point to avoid any lazy loaded logic from accidentally being pulled in to the final build. Having a separate directory allows the lazy loaded implementation to remain accessible from @ionic/angular for backwards compatibility.

Ionic developers can access this by importing from @ionic/angular/standalone.

src

This is where the lazy loaded component implementations live.

Ionic developers can access this by importing from @ionic/angular.
