Plasma packages are essentially kpackages, so use the macros from KPackage
to install Plasma packages.
This allows to reuse the facilities set up there.
REVIEW: 128579
In the SDDM theme (and a few other places) I leave some notes for other
developers; I need to add one to the workspace components too.
As plasma_package blindly copies everything it seems to annoy packagers.

At the moment, we could say that plasma is co-installable by chance,
it's only working because KF5 dropped the apps relative directory.
This change introduces a PLASMA_RELATIVE_DATA_INSTALL_DIR that will
be available to know where in share the components are and
PLASMA_DATA_INSTALL_DIR to know where data has to be installed to.
