Support eclass for packages that use KDE extra-cmake-modules.

This eclass is intended to streamline the creation of ebuilds for packages
that follow KDE upstream packaging conventions. It's primarily intended for
the three upstream release groups (Frameworks, Plasma, Applications) but
is also for any package that follows similar conventions.

This eclass unconditionally inherits cmake-utils.eclass and all its public
variables and helper functions (not phase functions) may be considered as part
of this eclass's API.

When used together with kde.org.eclass this will replace kde5.eclass and
kde5-functions.eclass, most of the latter is becoming obsolete.
