[bug#67428] [PATCH v2 09/12] gnu: Add cl-magicl

[Michal Atlas <michal_atlas+git@posteo.net>]

* gnu/packages/quantum.scm: New file.
* gnu/packages/quantum.scm: (sbcl-magicl, cl-magicl): New variables..

This package requires commencement, which already depends on
lisp-xyz in a way that breaks if they're mutually used,
this library is mainly the dependency of QVM (Quil Quantum Virtual Machine),
so I moved it into this separate file.
