refactor: finish stardust to fluent rename

[levithomason]

Breaking Changes

This PR only renames "Stardust UI" to "Fluent UI", including all variants. No other changes were made.

createComponent()

1. ✏️ Rename the render() callback param key from stardust to config:

   import { createComponent } from '@fluentui/react'
   
   createComponent({
   -   render({ stardust }) => {},
   +   render({ config }) => {},
   })

2. ✏️ Rename the typing CreateStardustComponentConfig to CreateComponentConfig.
3. ✏️ Rename the typing RenderStardustResultConfig to CreateComponentRenderConfig.
4. ✏️ Rename the className of the returned component from ui-stardust-component to fluent-ui-component.

💡 The displayName of the returned component was renamed from StardustComponent to FluentUIComponent. It is unlikely that your code relied on this displayName but we're including it here for completeness.

Theme

1. ✏️ Rename the StardustAnimationName typing to AnimationName.
2. ✏️ If you have a custom theme that maps required icon names to your icon names, the required icon names have changed their prefix from stardust-* to icon-*:

   const myTheme: ThemePrepared = createTheme({
     ...
     icons: {
   -  'stardust-checkmark': { isSvg: boolean, icon: SvgIconSpec },
   +  'icon-checkmark': { isSvg: boolean, icon: SvgIconSpec },
     ...
   }, 'my-theme')

Debug

✏️ Rename window.localStorage.stardustDebug to window.localStorage.fluentUIDebug, if you had enabled debug.

---

This PR finishes the work by renaming Stardust references to Fluent UI. We've renamed the repo and packages. We've also published the docs and packages under the new Fluent UI and @fluentui name.

Curious of the reasoning for using FluentUI rather than Fluent UI? I know that more directly matches the scope name, but I thought the lack of a dash in the scope name was just an unfortunate artifact of fluent-ui being taken already.

Per Joseph McLaughlin, they got a lot of feedback on the FluentUi initial idea and they changed the official guidance. It is now officially Fluent UI. 👍

He said he'd make an official announcement to the internal team today. Not sure if it happened yet. I do have the design guidance PDF if you'd like a copy 😄

Looks like this is a teams theme icon literally named iconCircle.
