support comment syntax for dynamic import chunkFileName

rollup is cool ! what i expected is to support comment syntax for dynamic import chunkFileName.

in webpack, we can write like import (/* myChunkFileName */ () => import('../../index.js'))

Feature Use Case

sometimes in project, need to organize all dynamic import to a configuration as blow

[
  {
     render: () => import("../../aaa/")
  },
  {
     render: () => import("../../bbb/")
  },
  {
     render: () => import("../../ccc/")
  },
]

output.chunkFileNames cannot work as expected cus chunks are all called 'index.js' (aaa/index.js bbb/index.js ...) , so output will something like index0 index1 index2 ...

Feature Proposal

is there any way to support comment syntax dynamic chunkFileNames or
any ideas to make it work based on current api ? it seems manualChunks cannot get the path parameter passed to dynamic import function

Start by reviewing Rollup's dynamic import handling and the output.chunkFileNames and manualChunks APIs described in the issue. Compare the requested comment syntax with the shown import examples and determine a supported design. Done means dynamic imports can express distinct chunk names without relying on index0, index1 naming.
