[Feature]: @tailwindcss/webpack support

[weihongyu12]

What problem does this feature solve?

I have seen that @tailwindcss/webpack has been released, boasting 2.17x faster performance compared to @tailwindcss/postcss.

Currently, in RSBuild, I am using it like this:

export default defineConfig({
    // ...
    bundlerChain: (chain, { CHAIN_ID }) => {
      chain.module
        .rule(CHAIN_ID.RULE.CSS)
        .oneOf(CHAIN_ID.ONE_OF.CSS_MAIN)
        .use('@tailwindcss/webpack')
        .loader('@tailwindcss/webpack');
    },
  },
});

I am wondering if there is a more elegant way to support it.

What does the proposed API look like?

Once this PR is merged, we plan to provide an Rsbuild plugin to support it: tailwindlabs/tailwindcss#20027
