Revert "[Closure GN] Convert simple WebUI Closure Compilation to GN."

This reverts commit 673e013b.

Reason for revert: http://crbug.com/833550

Original change's description:
> [Closure GN] Convert simple WebUI Closure Compilation to GN.
> 
> See go/closure-compile-gn for details.
> 
> This CL converts the Closure Compilation from GYP to GN for the following:
> - cryptotoken
> - download_internals
> - md_downloads
> - md_extensions
> - md_history
> - md_user_manager
> - offline_pages
> - signin
> - webapks
> - welcome
> 
> A local closure compile can be run by setting closure_compile = true in
> args.gn, and then running ninja -C out/Default webui_closure_compile.
> Individual projects can be compiled via, for example,
> ninja -C out/Default chrome/browser/resources/md_extensions:closure_compile
>
