Sergey Sharybin 03fd794130 Fix #109550: Cycles: OptiX not able to render without CUDA toolkit
Happens with specific GPUs like  NVIDIA A100-SXM4-40GB. They use the
compute capability 8.0, which is not explicitly compiled as a cubin,
and since 7fca0ee76a the PTX is not suitable for it either.

The safest solution is to revert the change to a known good state,
and re-iterate as needed.

Revert "Cycles: Increase the compute model for the PTX kernel"

This reverts commit 7fca0ee76a.

This change would need to be cherry-picked to the 3.6 LTS.
