[PRQ#41160] Deletion Request for gmic-no-opencv

MarsSeed [1] filed a deletion request for gmic-no-opencv [2]: I created this variant build of gmic, to exclude opencv support. I don't need this anymore, don't have time to maintain it, and no one seems to use it. Anyway it was more for me to experiment with builds. It does not bring any performance optimization. It only allows to remove opencv dependency, but nowadays the disk space it consumes is negligible in typical systems.
