Support for VK_NV_raw_access_chains

[drawoc]

Description of Feature

Hi. I'm currently working on an nvk implementation of VK_NV_raw_access_chains and trying to debug a performance issue with a game that I do not have which is running under vkd3d (Lego Builder's Journey) https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/38874#note_3232008 Taking captures of that game fails when VK_NV_raw_access_chains is available and used by vkd3d.

vkd3d automatically uses VK_NV_raw_access_chains when support is enabled in the driver, so I believe we need support in renderdoc if we want to continue using renderdoc for dx12 games once that feature lands.

It would be nice if renderdoc supported VK_NV_raw_access_chains.

Environment

• RenderDoc version: 1.41
• Operating System: Arch Linux
• Graphics API: Vulkan

Since this is just enabling a spirv capability, this seems to work if I just list the extension in renderdoc/driver/vulkan/vk_core.cpp

I think there is more required to fully support this extension and the SPIRV capability .

• The shader debugger would need changing to support the new SPIRV instruction.
• Bindless feedback and mesh output would need to be checked and perhaps updated to work with the new SPIRV instruction.
