[turbopack] add `experimental.turbopackChunking` config (#96398)
Built using @sokra's Fleet! This re-arranges all of our chunking
experimental features under `experimental.turbopackChunking` and adds
the following options:
```javascript
/**
* Avoid creating more than one chunk smaller than this size, in bytes. Smaller
* chunks are merged into bigger ones to avoid that. Defaults to `50000` (50 KB).
*/
minChunkSize?: number
/**
* Avoid creating more than this number of chunks per chunk group. Chunks are
* merged into bigger ones to avoid that. Defaults to `40`.
*/
maxChunkCountPerGroup?: number
/**
* Never merge chunks bigger than this size, in bytes, with other chunks. This keeps code
* in big chunks from being duplicated across multiple chunks. Defaults to `200000` (200 KB).
*/
maxMergeChunkSize?: number
/**
* Minimum size, in bytes, for a component chunk to be emitted on its own when
* `generateComponentChunks` is enabled. Component chunks smaller than this are folded into a
* single remainder chunk. Defaults to `20000` (20 KB).
*/
minComponentChunkSize?: number
```
