4cc32e65 - [SYCL][sycl-rel] Fix AddSecurityFlags having no side effects (#17796)

[SYCL][sycl-rel] Fix AddSecurityFlags having no side effects (#17796) This is a cherry-pick of intel/llvm#17690 --- CMake has a notion of scopes for variables and we fell into a pitfall of setting local variables instead of applying changes globally to the whole project.
