Alternate bundler: fix react refresh and adjust sourcemap (#77875)

- Fix failures in #77871 that
introduced by
rstackjs/rspack-plugin-react-refresh#22 (comment)
🤦
- Align the inject entry logic with webpack
- Use eval-source-map for rspack (before use source-map due to a rspack
bug #75981 (comment))
- Temporarily remove source-map ignoreList for rspack (will add it back
once rspack has built-in support)
