oa::core::memory::copy_streaming

Copy one complete byte slice using an explicit one-way streaming policy. The destination must not be consumed by the CPU soon. On a qualified x86-64 target, medium-sized copies use non-temporal stores. Other sizes use cached stores, preferring the platform routine above the small-copy range. Errors Returns an error when the slices have different lengths.
