[SYCL][HIP] Fix a Windows specific lit test failure on sycl-oneapi-gpu. (#7753)

Fix a Windows lit test failure. 
The issue is due to clang-offload-wrapper is slightly different on
Windows compared to Linux. This is not specific to recent update.
On Windows the argument of the clang-offload-wrapper looks like
"-compile-opts=--offload-arch=gfx??? --offload-arch=gfx???", while on
Linux that is "-compile-opts=--offload-arch=gfx???"
