feat(custom-elements): export ionicons/components

Also provide ionicons as a custom element which can be defined using `customElements.define()`

```
import { IonIcon } from "ionicons/components/ion-icon";
customElements.define("ion-icon", IonIcon);
```

The custom element build works the same as the lazy load build, and is also able to lazy load svgs on demand, either by giving it an exact url in the `src` attribute `<ion-icon src="./path/to/airplane.svg"></ion-icon>`, or by providing the name of the ionicon to load `<ion-icon name="airplane"></ion-icon>`.

If using the `name` attribute, you'll also need to set where to find the svg directory using `setAssetPath()`

```
import { setAssetPath } from "ionicons/components";
setAssetPath(location.href);
```
