Properly set properties of group_load/group_store to striped

Doing so exactly recovers the behavior of sub_group::load<vec_sz>,
sub_group::store<vec_sz> and eliminates warnings with 2025.1 and SYCLOS.

With this change, enable use of group_load, group_store for DPC++
compiler with `__SYCL_MAJOR_VERSION >= 8u` which includes
oneAPI DPC++ 2025.0.x compiler and SYCLOS bundle.
