Apply a random seed when NOT in benchmark mode to have 100% deterministic runs in all samples (#1127)

* Apply a random seed when NOT in benchmark mode to have 100% deterministic runs

These samples lack the check for benchmark.active when applying a random seed, which is done for other samples.

* Update texture3d.cpp

* Vulkan Example - Descriptor indexing (VK_EXT_descriptor_indexing)
*
* Demonstrates use of descriptor indexing to dynamically index into a variable sized array of images
*
*
* The sample renders multiple objects with the index of the texture (descriptor) to use passed as a vertex attribute (aka "descriptor indexing")
*
*
* Relevant code parts are marked with [POI]
