Set the recursion depth for chit and miss cases

In the new dEQP-VK.binding_model.descriptor_update.acceleration_structure.ray_tracing.*
group of tests the "chit" and "miss" variants the shaders
generate additional rays, which means their recursion depth needs to be
greater than 1. In both cases "2" covers it.

Affects:

dEQP-VK.binding_model.descriptor_update.acceleration_structure.*

Components: Vulkan

VK-GL-CTS issue: 2924
