feat(webpack): webpack 5 support

[paradite]

webpack 5 moved some stuff around: https://webpack.js.org/blog/2020-10-10-webpack-5-release/#module-and-chunk-graph

specifically:

• module.providedExports -> compilation.chunkGraph.moduleGraph.getProvidedExports(module)
  • https://github.com/webpack/webpack/blob/a5821c74568d59a330043900328a018c5d3a4af7/types.d.ts#L6484
• module.usedExports -> compilation.chunkGraph.moduleGraph.getUsedExports(module, runtime)
  • https://github.com/webpack/webpack/blob/a5821c74568d59a330043900328a018c5d3a4af7/types.d.ts#L6492
  • the return type has been change to null | boolean | SortableSet<string> (no longer Array)

Hi @MQuy, since this is merged, can we have a new npm version release as well? Thanks.
