[SYCL] Add /OPT:NOREF on Windows when -fsycl-allow-device-image-dependencies is used (#21929) 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.
