[SYCL] Fix output of fsycl-host-compiler-win.cpp when clang++ is used (#1316)

fsycl-host-compiler-win.cpp currently assumes that clang-cl will be used
on Windows, while there is no guarantee for that. This commit changes
the test to use the -o option for output, which will work on both
clang-cl and clang++, instead of /Fe which is only supported by
clang-cl.
