Handle dpnp functions and tests to run on CUDA devices (#2075)

This PR suggests updating some function implementations and tests to run
on CUDA devices
The PR includes:
1. Raise NotImplemetedError for unsupported functions
2. Create **skipped_tests_cuda.tbl** for unsupported functions
3. Skipped tests with a bug ticket for functions that should run on CUDA
4. Implement **is_cuda_backend()** and **is_cuda_device()** to determine
that the object has a CUDA backend and that the tests run on CUDA
