preview command adds cross support

[289420843]

What problem does this feature solve?

cross-domain access to resource files is supported.

What does the proposed API look like?

farm.config add previewServer config

export default defineConfig({
  server: {
    ...
  },
  previewServer:{
    headers: {
      "Access-Control-Allow-Origin": "*",
    },
    ...
  }
}

or reuse server config.
