Subject: Adding sycl backend for TensorPadding.h; disbaling __unit128 for sycl
 in TensorIntDiv.h; disabling cashsize for sycl in tensorDeviceDefault.h;
 adding sycl backend for StrideSliceOP ; removing sycl compiler warning for
 creating an array of size 0 in CXX11Meta.h; cleaning up the sycl backend
 code.
