[OpenMP] [cmake] Don't use -fno-semantic-interposition on Windows (#81113)
This was added in 4b7beab4187ab0766c3d7b272511d5751431a8da. When the
flag was added implicitly elsewhere, it was added via
llvm/cmake/modules/HandleLLVMOptions.cmake, where it wasn't added on
Windows/Cygwin targets.
This avoids one warning per object file in OpenMP.
