When bundle file, how keep import syntax instead of webpack_require and emit chunk

[njzydark]

Because vite handle barrel files has big performance problem, the rspack/rsbuild/rslib can handle it correctly, so i want use rslib to prebundle test file for vitest, but current has some limitations:

vitest module mock can't work, becase vitest use custom vite plugin to transform import syntax, but when use rslib to prebundle file, the output has no import syntax, it use webpack_require

const { a } = await Promise.resolve().then(__webpack_require__.bind(__webpack_require__, "./src/index.ts"));

this is demo repo: https://github.com/njzydark/rslib-vitest-prebundle-demo

./index is bundled so it's using webpack_require, what kind of output are you expecting?
