Pass codeSplitting generated filenames to onwrite hooks

[Andarist]

In case of codeSplitting there is no way to know what file got generated when it gets called and it's useful for onwrite hook

Thanks - this is a great approach, I'm just considering the plugin hooks around code splitting at the moment, and would like to put a bit more thought to the state contract of plugins. I'm even wondering if an asset emission API may make more sense here since we might need that for WASM as well. Will aim to come up with some feedback soon in reference to this. Further discussion welcome too.

I've posted #2126 to provide this functionality, where chunk.name effectively provides the same information.

Hi @Andarist, as #2208 (which is basically the revised version of #2126) has now been merged and released, does this meet your requirements and can this one be closed?

I'm not entirely sure, this was just a minor issue that I've noticed once. If I come across this issue again then gonna report it, for now I would consider this to be solved.
