vkGetAccelerationStructureHandleNV

To allow constructing geometry instances with device code if desired, we need to be able to query an opaque handle for an acceleration structure. This handle is a value of 8 bytes. To get this handle, call:

VkResult vkGetAccelerationStructureHandleNV(
    VkDevice device,
    VkAccelerationStructureNV accelerationStructure,
    size_t dataSize,
    void* pData);

• device is the logical device that owns the acceleration structures.
• accelerationStructure is the acceleration structure.
• dataSize is the size in bytes of the buffer pointed to by pData.
• pData is a pointer to an application-allocated buffer where the results will be written.
