Similar to the regression tests it is possible to append -RT suffix
to the compute type to enable hardware ray-tracing.
For example HIP_0 will run benchmark on first HIP device without
hardware ray-tracing, HIP-RT_0 will run benchmark on the same device
but will enable hardware ray-tracing.
The downside of this change is that it will make it so METAL device
will no longer use HW-RT on M3 and aboce, and explicit METAL-RT is
to be used. This is because benchmark was relying on the Auto
configuration which has different behavior depending on the device
generation.
