[SYCL] Add /OPT:NOREF on Windows when -fsycl-allow-device-image-dependencies is used

[srividya-sundaram]

When -fsycl-allow-device-image-dependencies is used, linked libraries may
contain device-side symbols that are required only for SYCL device image
resolution and are not referenced directly from host code.

On Windows, linker optimization /OPT:REF may discard such seemingly unused
import-library references, causing required device image dependencies to be
dropped from the final executable. This can lead to runtime failures such
as "No device image found" when external device images (for example from
oneMKL device API DLLs) are needed.

Add /OPT:NOREF when -fsycl-allow-device-image-dependencies is present to preserve these
dependencies and ensure correct runtime device image discovery.

For this particular test case, having -- %s /link /opt:ref makes everything after it treated as input files not options.

And having /link /opt:ref before -- %s captures all remaining arguments after it as linker arguments

And finally /link is needed to pass /OPT:REF in clang-cl, without it, we get warning: argument unused during compilation: '/OPT:REF' - it's ignored, doesn't reach the linker.
