05acd20a - convert singrad to function op and remove cpu kernel (#13263)

convert singrad to function op and remove cpu kernel (#13263) ### Description Implemented gradient of sin as a function op. ### Motivation and Context Sin gradient currently implemented as cpu op which could hurt performance. ### Testing built ORT from source: `./build.sh --config RelWithDebInfo --enable_training --use_cuda --cuda_home /usr/local/cuda --cudnn_home /usr/local/cuda --build_wheel --parallel --skip_tests` tested SinGrad implementation: `cd build/Linux/RelWithDebInfo/ && ./onnxruntime_test_all --gtest_filter=GradientCheckerTest.SinGrad` Co-authored-by: Prathik Rao <prathikrao@microsoft.com> Co-authored-by: Baiju Meswani <bmeswani@microsoft.com>
