Extend binding model tests

Extend binding model tests

Extend tests with shaders proposed by VK_KHR_ray_tracing.

Add tests:
 * dEQP-VK.binding_model.descriptorset_random.*.rgen.*
 * dEQP-VK.binding_model.descriptorset_random.*.sect*
 * dEQP-VK.binding_model.descriptorset_random.*.ahit.*
 * dEQP-VK.binding_model.descriptorset_random.*.chit.*
 * dEQP-VK.binding_model.descriptorset_random.*.miss.*
 * dEQP-VK.binding_model.descriptorset_random.*.call.*

Rename tests:
 * dEQP-VK.binding_model.descriptorset_random.*.rgen.*
to:
 * dEQP-VK.binding_model.descriptorset_random.*.rgnv.*
