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.ludic — Vk.*: Vulkan for Ludic.
#
# Every command of Vulkan 1.0-1.4 and of the extensions the render3d Vulkan renderer
# is built around is bound in vk_api.ludic (generated by `ludic-dev vkgen` from the
# Vulkan registry), with every constant and every struct's size and field offsets.
# Vk.<snake_name>(...) calls one: Vk.create_instance(info, null, out). Structs are
# plain memory filled by field name:
# let ci = bytes(VkInstanceCreateInfo_sizeof)
# Vk.zero(ci, VkInstanceCreateInfo_sizeof)
# Vk.put_i32(ci, VkInstanceCreateInfo_sType, VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO)
#
# Numbers: a C float is float bits in an int; uint64_t, VkDeviceSize and
# non-dispatchable handles are `long`. A negative long has to come from a `long`
# variable - an int literal passed straight to a long parameter is zero-extended.
#
# The loader is opened at run time by Vk.open() (vk_win.ll / vk_mac.ll), never
# linked: 0 means this machine has no Vulkan, and the program carries on without it.
