Cycles: Make Embree compact BVH optional
Make the Embree RTC_SCENE_FLAG_COMPACT flag optional and enabled per default.
Disabling it makes CPU rendering a bit faster in some scenes at the cost of a higher memory usage.
Barbershop renders about 3% faster, victor about 4% on CPU with compact BVH disabled.
