feat: worker support

[ahabhgk]

Summary

resolve #3074

checkout example/worker for example

Feature:

• output.workerChunkLoading
• output.workerWasmLoading
• output.workerPublicPath
• worker with output.module: true

Todo:

• webpackEntryOptions magic comments (low priority)
• custom worker syntax #3656 (low priority, block by align parser hooks with webpack: multi hooks in one visitor instead of multi visitor #3619)
• Can't resolve ./worker.js in './index.js' when treeShaking enabled #3658 not work with tree shaking, will fix it in next PR

Test Plan

example/worker works, and some tests block by #3658, #3655, #2408, will add more tests after blockers resolved
