build: restructure demo-app in favor of bazel

Restructures the demo-app by no longer mixing up the `demo-app` name.

Currently the `demo-app` consists of two parts:

  * The demo-app
  * And the accessibility demos

As you can tell above, this is pretty much confusing because it's
technically just consisting of:

  * Accessibility demos
  * Library demos

This change cleans up the naming and makes sure that the modules are
structured in a best-practice way.

It's odd to have the `DemoAppModule` (*not the root module*) that
includes all library demos as a folder next to the actual demo
components.

This makes it extremely hard to convert the demo-app to Bazel because
we cannot target all `.ts` files through `glob` because it only matches
files inside of the same folder (or Bazel package).

In order to make it easy to run the demo-app with Bazel, and to just
clean it up, the folder structure should be as followed:

```
src/demo-app/
  | a11y-demos/
     | ...
     | BUILD.bazel
  | library-demos/
     | ...
     | BUILD.bazel
  | index.html
  | BUILD.bazel
```
