VK_LAYER_KHRONOS_validation "Check Out of Bounds" causes invaildation of descriptor set when using descriptor buffers.

[codecnotsupported]

Environment:

• OS: Linux
• GPU: Nvidia Geforce 1060 3GB
• SDK or header version if building from repo: SDK, 1.3.243.0
• Options enabled (synchronization, best practices, etc.): VK_LAYER_KHRONOS_validation->GPU-base (GPU-assisted)->Check Out of Bounds

Describe the Issue

The Check Out of Bounds option in the VK_LAYER_KHRONOS_validation causes descriptor to be invalid when using descriptor buffers.

This can be verified by running the desciptor_buffer_basic sample from Vulkan-Samples with the "Check Out of Bounds" option enabled in Vulkan Configurator.

Note: The Imgui overlay still works fine in the sample, which uses vkCmdBindDescriptorSets, which might mean that Check Out of Bounds is only using vkCmdBindDescriptorSets instead of vkCmdBindDescriptorBuffersEXT & vkCmdSetDescriptorBufferOffsetsEXT when descriptor buffers are used. Causing the descriptor set to be invalidated.

Expected behavior

I expect a warning that descriptor buffers aren't supported at the very least. Otherwise support for descriptor buffers would be nice.

Additional context N/A

[codecnotsupported]

Check descriptor indexing accesses causes the same issue. But only in my test application, it doesn't affect the desciptor_buffer_basic sample.

Descriptor buffer GPU-AV is a work in progress. I've been meaning to add a warning for a while. Added in #6030
