magma now extends CudaPackage class, taking care of the gcc conflicts (#14471)

Browse source 
* magma now extends CudaPackage class, taking care of the gcc conflicts

* enforce +cuda; thus cuda is dependency via CudaPackage class

* add conflict

* use cuda_arch to set GPU_TARGET build option

* get rid of unnecessary constraint

* flake8

* impose cuda version dependency found empirically

* add variant description

* add conflict
