feat: reduce bundle size in combination with icons

[danielleroux]

🆕 What is the new behavior?

• Naming imports like `<IxIcon name="star" /> are not supported any more. (Reducing bundle size and chunk loading)
• Naming imports like <ix-icon name="star"></ix-icon> requires a additional configuration entry inside the angular.json. (or similar entry for none angular projects)
