New package: maloc (#16631)

* [maloc] created template

* [maloc] added some build dependencies

* [maloc] added homepage and description

* [maloc] added doc variant in an attempt to disable documentation. Still builds doc though... at least when there is a system doxygen found. Having doxygen being a dependency here can bring python in and cause issues for dependents, even when listed as only a build dependency. Maybe this is a bug?

* [maloc] flake8 and fixme removal

* [maloc] shorted description
