Have the option to run emacs as --daemon in brew services

[MuhmdRaouf]

Feature request description

Hello, I have installed Emacs and enabled brew services as well, then realized that in /opt/homebrew/Cellar/emacs-plus@29/29.4/[email protected] it work as --fg-daemon can we add a flag while build to give us the ability to make it run as --daemon/--bg-daemon, as after I have change it and restart the service emacs loading became much faster (using doom emacs)

credit to the idea came from this comment in this gist https://gist.github.com/redinger/1394910?permalink_comment_id=5001180#gistcomment-5001180
