using a [babel plugin](https://gist.github.com/pengx17/49e24ae8a5a609bdaff122ee8c679d1c) to transform all var(--affine-xxx) to cssVar
Some issues:
- tried ast-grep but it seems to be not easy to add imports conditionally
- current work does not work well with ts with types because babel will strip them out
A React wrapper for blocksuite editor from title/meta/doc/edgless fragments.
This PR only **clones** the `AffineEditorContainer`'s existing behavior and make it easier for extension in affine later.
fix TOV-315
### Some core issues:
A customized version of `createComponent` from `@lit/react`. The [existing and solutions in the community](https://github.com/lit/lit/issues/4435) does not work well in our case.
Alternatively in this PR the approach we have is to create web component instances in React lifecycle and then append them to DOM. However this make it hard to wrap the exported Lit component's using React and therefore we will have an additional wrapper tag for the wrapped web component.
To mitigate the migration issue on using React instead of Lit listed on last day, we now use [a proxy to mimic the wrapped React component](https://github.com/toeverything/AFFiNE/pull/5606/files#diff-5b7f0ae7b52a08739d50e78e9ec803c26ff3d3e5437581c692add0de12d3ede5R142-R183) into an `AffineEditorContainer` instance.
Add color-scheme to html so that the web will use system scheme when scripts has not being loaded;
Use `(prefers-color-scheme: dark)` so that the css vars do not defer load based on `data-theme`, which is set by next-themes (which is deferred).
