feat(vk): call shapes for the acceleration-structure commands the interposer lacks

Browse source 
NVIDIA Streamline's interposer exports none of VK_KHR_acceleration_structure's
commands, so ray tracing looks each up per device with vkGetDeviceProcAddr and
calls it through a pointer: create (four pointers -> result), destroy (device,
handle, allocator), build sizes (device, type, info, counts, sizes), the
command-buffer build (buffer, count, infos, ranges) and the device address
(device, info -> u64). Both runtimes assemble; nothing uses them yet.
