Fix pages react alias (#50128)
Fix react and react-dom aliases are not properly set for `pages/`
* Remove alias react-dom internals to `{}` in edge runtime as we're using server rendering stub as alias
* Add `react$`, `react-dom$` missing aliases
* Only apply alias to builtin react/react-dom when it's app dir assets.
* Add `react|react-dom/package.json` resolving to require-hook
* Fix hmr issue that sometimes it will perform a reload when a hard navigation is triggered
