OMP_MAP_SELF ensures that a variable is used directly on the device without
creating a new copy. As per my understanding, OMP_MAP_LITERAL works for
pointers, but it doesn’t guarantee they point to device-accessible memory. This
is especially useful for USM, where we don’t want unnecessary mappings.
