feat(splitting): support minChunkSize option

[ArrayZoneYour]

fix #2901, #2419, related to #207

When there are many entry points, it is easy to generate some small chunks.

This MR try to land minChunkSize options to control the chunk size by source content size

@evanw This would be really high-impact for my team, as I believe that chunk size is the only thing preventing us from switching from Rollup to esbuild. You mentioned that you intended to eventually rework the linker to support more customizable chunking behavior -- would you be open to merging this solution as a stopgap for now?

I tried to locally compile this and test it with out project, however, the result is not working. After enabling the minChunkSize some of the imports are no longer working. In my case the require_prop_types is not defined.

@fochlac Can you provide a minimal reproducible use case?
