Support for descriptorBufferCaptureReplay feature of VK_EXT_descriptor_buffer..

[oscarbg]

Hi,
similar request to my other Renderdoc raytracing capture issue:
#390
but for another extension..

EDIT: note Renderdoc still doesn't support it.. but there is an open issue:
baldurk/renderdoc#2880

capturing any app using VK_EXT_descriptor_buffer like for example:

https://github.com/KhronosGroup/Vulkan-Samples/tree/main/samples/extensions/descriptor_buffer_basic
is unsupported in Renderdoc using AMDVLK due to unsupported descriptorBufferCaptureReplay..
see latest AMDVLK driver report:
https://vulkan.gpuinfo.org/displayreport.php?id=35585#features_extensions
Renderdoc supports VK_EXT_descriptor_buffer: https://github.com/baldurk/renderdoc/blob/v1.x/renderdoc/driver/vulkan/extension_support.md
also descriptorBufferCaptureReplay is supported by other drivers like NV for example..
