fix(turbopack): webpack-loaders failed to resolve relative path (#82720)
fixed: #82106
The error was cause by the follow reason, when pass:
```ts
const nextConfig: NextConfig = {
/* config options here */
turbopack: {
rules: {
'*.txt': {
loaders: ['./test-file-loader.js'],
as: '*.js',
},
}
}
};
```
and the project directory as follows:
```bash
src
|_ app
|_ index.tsx
|_ text.txt
```
The loader will deal the `text.txt` under `src/app`, then the loader
will resolve path like:
```ts
require.resolve('./test-file-loader.js', paths: ['/Users/next-app/src/app'])
```
Because the resource dir the `dirname(resoucePath)`, and the
resourcePath is `/Users/next-app/src/app/text.txt`, this will never
resolve the right loader path here.
So I just add a more `path` param(which is `contextDir`) for the
require.resolve function, it will help the loader to find the right path
here.
