They are the systemd translated versions of what the udev rules
create.  Effectively, dev-dvb-adapter0-frontend0.device is just a
translation of /dev/dvb/adapter0/frontend0.  The udev rules expose
that information to systemd somehow - I have never delved into how it
works.  But systemd now has that .device unit which it can query:

root at mypvr:/etc/udev/rules.d# systemctl status
? dev-dvb-adapter0-frontend0.device - /dev/dvb/adapter0/frontend0
   Follow: unit currently follows state of
     Loaded: loaded
     Active: active (plugged) since Sat 2022-11-05 00:11:45 NZDT; 20h
