workers: proper TS libs, more spec-compliant APIs (#3812)

* split lib.deno_main.d.ts into:
  - lib.deno.shared_globals.d.ts
  - lib.deno.window.d.ts
  - lib.deno.worker.d.ts
* remove no longer used libs:
  - lib.deno_main.d.ts
  - lib.deno_worker.d.ts
* change module loading to use proper TS library for compilation
* align to Worker API spec:
  - Worker.terminate()
  - self.close()
  - self.name
