LOG: [mlir] Don't emit forward declaration for user defined storage classes

Currently DefGen::emitDecl always emits forward declarations of storage classes even for user define ones, which makes it difficult to use template class directly in ODS. This patch changes `DefGen` not to emit forward decl when `genStorageClass` is false.
