[bug#70460] [PATCH 0/4] Update power-profiles-daemon and add a service-type for it.

[Dariqq]

Hi Guix,

Here are a couple of patches that update the power-profiles-daemon to the 
latest release and add a corresponding service for it which will make changing 
power-profiles available in DEs like GNOME or via the cli tool.

I am not sure if some of the python dependencies should be normal inputs rather 
than native inputs.

The package will now also build the shell completions, manpage, docs and skip 
installing the systemd unit.
Also I was not sure if the gtk-docs should go to a seperate doc output but this 
corresponds to ~0.2 MB so I didn't bother.

The daemon is supposed to be a systemd unit started via dbus but just 
autostarting a similiar shepherd service seems fine as well and is what other 
distros without systemd do (i.e gentoo or void linux).

I've also tried to patch the dbus service definiton to run the daemon directly 
and it seems to work as well which would make the shepherd service obsolete. I 
am not sure what the better solution is.

The systemd unit specifies a 'conflict' with other power-management services 
like tlp but I don't think something similiar can be done for the shepherd 
right now.

The service-type is a rather simple and has the following extensions:
shepherd: Run the daemon.
dbus: Make the name of the service available.
polkit: Allow normal users to change power profile.
profile: Make the cli tool available.
activation: Create a directory.

As this is my first time writing a service-type any feedback would be greatly 
appreciated.

This would fix #69061.
