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`
