Camillo Bruni f2d079bc97 [tools][system-analyzer] Add local symbol server
Start a local symbol server using the local-web-sever node package:
   ws --stack system-analyzer/lws-middleware.js lws-static cors

The system-analyzer will then use it to symbolize profiles.

Note: The symbol server will execute `nm` and `objdump` locally.
