Migrate to rsbuild and swc

[RichDom2185]

• Closes Migrate to Vite #2933.
• Closes Clean up codebase post-migration to Vite/React19 #2990.
• Supersedes Migrate to Vite #2996.

---

Description

CRA is dead. Switch to rsbuild (which uses rspack → drop-in for webpack → powers CRA), but written in Rust so much faster.

• Switch to rsbuild for performance and maintenance
• Upgrade jest from v27 to v29
• Switch to swc parser (also happens to be written in rust lol) for jest for performance
• Remove CRA and CRACO

Type of change

• Code quality improvements

How to test

Everything should (and does) still work since it's effectively drop in.

Checklist

• I have tested this code
• I have updated the documentation

Did a preliminary quick review of the code changes, although I'm not too sure for the testing updates. As long as they are passing (which they appear to do so), I think it should not be too far off.

I have also yet to run the code locally, so here are just some questions and ideas from me after glancing over the changes, let me know what you think!

Previously with Webpack it would compile away the dynamic import used to import modules (because there was no way to webpack-ignore something in js-slang). Should I check if js-slang can be switched away from using the function constructor, or should we leave things as is?

@leeyi45 I think I saw this comment somewhere, but wasn't too sure what it entailed in terms of testing.

I had tried running some module code in the playground and it seems to work, though I'm not sure if that is what you mean.

Would you mind checking as well? Thank you!

Did a quick review. I think on the js-slang side we should move toward building for ESM rather than CommonJS, which would make this change easier. Either ways, I've put the ignore warnings config back in for the dynamic module import

Tested yarn start and yarn build locally with no issues found. LGTM!

Will we need these commented code in the future?

It's mainly kept as reference since the original file was deleted (so it would be hard to get a "file history" since the old webpack config won't be present in the current repo anymore).

Now that this PR is merged, it's free to be deleted as one can always look at the file history of rsbuild.config.ts to easily see what the original webpack config was
