introduces the backend specific headers "sycl/backend/<backend_name>.hpp"
CTS tests assume that if backend macro is defined (e.g. SYCL_BACKEND_OPENCL)
it is fully functional without extra includes. So the patch adds
include of the backend specific header when the backend is enabled.

The change should fix the recent massive failure of CTS tests with the error:
implicit instantiation of undefined template 'sycl::interop<sycl::backend::opencl, sycl::platform>'
