3cae3021 - Add tests for C++ functional cosine_similarity and pairwise_distance, and clean up functional test code (#26559)

Add tests for C++ functional cosine_similarity and pairwise_distance, and clean up functional test code (#26559) Summary: This ensures that `F::cosine_similarity` and `F::pairwise_distance` can be used simply by including `torch/torch.h` and set `namespace F = torch::nn::functional`.
