[clang] [NFC][clang] Fix CodeGenSYCL::unique_stable_name_windows_diff test (PR #146854)

[Mariya Podchishchaeva via cfe-commits]

https://github.com/Fznamznon created https://github.com/llvm/llvm-project/pull/146854

The test checks x86 target in fsycl-is-device mode. x86 is not a valid offloading target and IMO test meant to check fsycl-is-host mode to make sure host invocations of __builtin_sycl_unique_stable_name work correctly. This also switches the test to use sycl_entry_point attribute instead of sycl_kernel because the intention for the future SYCL changes is to use sycl_entry_point and eventually remove sycl_kernel attribute when sycl_entry_point supports enough SYCL cases.

 test

The test checks x86 target in fsycl-is-device mode. x86 is not a valid
offloading target and IMO test meant to check fsycl-is-host mode to make
sure host invocations of __builtin_sycl_unique_stable_name work
correctly.
