At the moment most of our APIs are tied to @itwin/components-react package. This has the following drawbacks:

• Peer dependency on appui packages.
• APIs can only be used or are only convenient to use with components from appui packages.

Need to provide component-agnostic APIs for all our components - this will allow:

• Drop appui peer dependencies (some may need to stay as simple dependencies, but that's much better than peer).
• Consumers to use our APIs with components other than the ones in appui.
