Remove unnecessary copies of Scalars for TensorBody template (#92162)
Inspired by #92156 , I realized our generated TensorBody.h has many methods that do an unnecessary copies. Scalar is backed by a ptr and is therefore not trivially copyable and care should be assigned over ownership of the params. Since it's a template, clang-tidy was never run on it in a way that was able to propogate the changes back to the source code.
