feat: remove v2 web components and replace with visually aligned v3 alpha web components

[chrisdholt]

Current Behavior

This PR updates the web components package to remove existing components and add initial implementations of Fluent UI token and visually aligned implementations. This PR is the initial commit for the v3 release branch. A big win for One Microsoft! There is still work to do here, including updating to new templates from FAST Foundation, and updating to leverage FAST Element 2.0 - but this starts the process of migrating to components which implement the current Fluent UI specs and design tokens.

curious why was this added ? react-theme latest is 9.0.0-rc.4 so I'd suggest we use that one, thus removing this entry to prevent dupes.

[chrisdholt]

@Hotell ideally I don't want to take the dependency on "react-theme", we'd likely prefer to just have a set of tokens, with defaults. This will go away, but we needed to ensure we had interop w/ the React Theme Provider in the demo, and this is where the tokens currently come from.

I'll look to update and drop this dependency.

[Hotell]

sounds good, we should spin a new package just for tokens that will be platform/rendering layer agnostic. WDYT ?

This is stage one of a few. We need to drop the dependency on the current react-theme package and migrate to one with just the tokens ideally. We also have some cleanup and testing to do as the initial work provided here is an initial "stage" for the release branch. We don't have a firm date yet, but hopefully we can get a beta out soon!
