Extend the systemd service so that it can be used for tuning the Energy
Performance Preference (EPP) as well. Available options can be read from
/sys/devices/system/cpu/cpufreq/policy0/energy_performance_available_preferences.
The desired one can then be set in cpupower-service.conf.

One of the most typical use cases of the 'cpupower' utility works as
follows: run 'cpupower' at boot with the desired command-line options
and then forget about it.

Add a systemd service (disabled by default) that automates this use
case (for environments where the initialization system is 'systemd'),
by running 'cpupower' at boot with the settings read from a default
configuration file.

The systemd service, the associated support script and the
corresponding default configuration file are derived from what is
provided by the Arch Linux package (under "GPL-2.0-or-later" terms),
modernized and enhanced in various ways (the script has also been
checked with 'shellcheck').
