feat(vk): Vk.* - Vulkan 1.0-1.4 generated from the registry, loaded at run time

Browse source 
ludic-dev vkgen reads vk.xml into runtime/native/vk_api.ludic (constants, every struct's
<Struct>_sizeof and <Struct>_<field> offsets, one extern per command) and vk_thunks.ll.
Every size and offset was compiled against the SDK's C headers; `ludic-dev test` checks the
tracked files against the registry wherever the Vulkan SDK is installed.

vk_win.ll (vulkan-1.dll) and vk_mac.ll (libvulkan.1.dylib, MoltenVK) open the loader at run
time, so a program built with Vk.* starts on a machine without Vulkan. ludicc and ludic
build link both for any program that uses Vk.*. The seeds are regenerated for the new
compiler.

vk_probe reports what a machine's Vulkan can do; vk_compute dispatches a Slang compute
shader and reads the picture back, clean under the validation layer on an RTX 3070 Ti and
on an M4 Pro through MoltenVK.

# Vk.* links the generated thunks and the loader that fills them at run time:
# vk_win.ll (vulkan-1.dll) on Windows, vk_mac.ll (libvulkan.1.dylib, MoltenVK) on
# macOS. Neither links a Vulkan library, so the program starts without one.
