Initially introduced in apache#16183, these changes were reverted in apache#17252 due to performance degredation in some Relax models. This could occur when a model contained a large number of calls to `"vm.builtin.tuple_getitem"`, which may occur when model weights are provided as a tuple. This PR re-applies the changes from apache#16183, but with the performance degredation resolved. The root cause was unnecessary type-checking when converting from an untyped `tvm::ArrayNode*` to the typed `tvm::Array<T>`, in the case where `T` is `ObjectRef`.
