syncthing: use service files from upstream

Currently only for the user services as NixOS handles the named system
instances slightly differently.

syncthing and syncthing-inotify are done the same way.

There are 4 parts to this:

 1) Copy in the upstream unit files
 2) Make the nixos module use the definition from upstream
 3) Enable restarting of all instances (system and user) on resume
 4) Allow the traffic in the firewall on default ports if wanted

fixes #18973

Open the default ports in the firewall:
- TCP 22000 for transfers
- UDP 21027 for discovery
If multiple users are running syncthing on this machine, you will need to manually open a set of ports for each instance and leave this disabled.
Alternatively, if are running only a single instance on this machine using the default ports, enable this.
