[SYCL] Fix macro in device library function declaration (#1324)

As our compiler are based on LLVM , so:
"if defined(__GNUC__) || defined(__clang__)" will always be true as __clang__ will always be defined
and "elif defined(_MSC_VER)" will always be false as only _MSC_VER is a Microsoft CL compiler's macro telling its version. Current code will lead to std::assert building failure on Windows.
