Cycles: use packed float3 back for oneAPI
This fixes a 15% performance regression silently introduced by
79ab76e156d4bde937335be784cdf220294600d5 that aligned the compact
float3 on 16 bytes for oneAPI.
Current change is minimalist, there are further cleanup opportunities
such as removing packed_float3 definition for oneAPI but for some
reason, it cuts the recovered speedup in half, so we're starting with
this small fix for now.
