Descriptor Indexing test is missing tests for VK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR

[Jasper-Bekkers]

Hi all,

We, in our app, are using bindless TLAS-es quite a bit and over the years we've had to work with pretty much every hardware developer to make sure that this works. On some platforms this is more fine then others (for example: Android, not so fine since drivers rarely get updated).

It looks like the CTS test contains no tests for VK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR in https://github.com/KhronosGroup/VK-GL-CTS/blob/9d4d21644776412798f3bdb49ba3c3e42af15436/external/vulkancts/modules/vulkan/descriptor_indexing/vktDescriptorSetsIndexingTests.cpp while I do think this ought to be added & tested since it's widely supported.
