Update submission tools for mux

1. don't generate user_project_wrapper.v, as it's now static
2. don't generate macros.cfg, as gen_macro_cfg.py does it (eventually, we'll want to integrate it into tt-support-tools)
3. don't generate PDN hooks config. Instead, we're using a wildcard to match all user macros.
4. remove the "layout" section from config.yaml, and scanchain related stuff from generate config.json
