09ad464d - Change activation modules in C++ from using Tensor& to Tensor (#28501)

Change activation modules in C++ from using Tensor& to Tensor (#28501) Summary: Sequential does not like modules added to it to take Tensor& (const Tensor& and Tensor are both OK). Functional and others use Tensor when they want to potentially change things in-place. This changes ReLU and friends to also do that. Unfortunately, this seems to be BC breaking on the ABI level. On the other hand, use of the module ReLU seems rare enough outside Sequential (in particular in C++ models, the standard seems to be to use torch::relu instead). is the BC breaking OK here?
