Add code generation test for CONSTANT block (#981)

* code generation is already implemented in https://github.com/BlueBrain/nmodl/blob/25cd4707d2a4cf7f47febeb9ba321ff2dc30244c/src/codegen/codegen_helper_visitor.cpp#L158 https://github.com/BlueBrain/nmodl/blob/9602bddb83c55a0a3cb64661b156bb37270fdaaf/src/codegen/codegen_cpp_visitor.cpp#L2606 * add test to make sure variables are added as part of mech_Store struct that contain all global variables fixes #945 Co-authored-by: Ioannis Magkanaris <[email protected]>
