This is far less code and allows for an easier enforcing of standards, for
example the name of the log identifiers which were adjusted in a few cases.
Also clean up unused includes when noticed.
This makes it easier to read, because we do not have to handle a list of
files that get added to the targets. In other KDE projects, we also
prefer the target centric approach.
In case one wants to reuse the same category in multiple places, it
would be best to create a small static lib. But for now, this is not
needed.
The moc process already rebuilds the plugin when the JSON file changes, consequently the additional parameter is not needed.

This automatizes the generation of logging categories so a
kdeconnect-kde.categories is generated and installed to
/usr/share/qlogging-categories5/ so kdebugsettings can use it.
Also, sets the default logging level to Warning. So now the logs
of users won't be filled with debug messages but they can
modify the configuration easily with kdebugsettings.
Summary: Current code only supports one player
Test Plan: Run two media sessions. Dbus inspection works fine, UI has some issues with values not updated, but out of scope for this diff
