Introduce a new option for workers chunks' filenames

[gretzkiy]

Feature request

The source of this feature request is this discussion. The aim is to specify the filename for worker chunks only. Currently, there is no straightforward way to determine whether the chunk being processed in chunkFilename is a worker. Therefore, the request is for an option similar to workerPublicPath, but only for the worker chunk's filename, such as workerChunkFilename.

During the aforementioned discussion, @alexander-akait suggested identifying worker chunks by checking if chunkLoading === 'import-scripts' in pathData?.chunk?._groups within the chunkFilename function. However, this approach is considered hacky and not very robust.

So my understanding is that the output.workerPublicPath feature is not enough?

[alexander-akait]

@TheLarkInn No, it only set public path for workers, but sometimes you need another location for workers than dist, right now you can implement this using chunkFilename: (pathData) => { /* ... */ }, but it is really hard to undestand when chunk is worker's chunks when not, so it is more like about user experience
