feat(render3d): 22.10 - ludic.render3d carries MoltenVK, so a Mac program has its Vulkan driver

Browse source 
native/build.sh builds MoltenVK v1.4.2 from its pinned, checksummed tag (its dependencies at the
commits its ExternalRevisions pins), thinned to arm64, id @rpath/libMoltenVK.dylib, signed ad hoc;
its licence goes in native/LICENSE-MoltenVK. Every render3d program links it through its rpath -
the package's lib/ while developing, Contents/Frameworks in a bundle, where ludic bundle puts and
signs it - and vk_mac.ll also looks for @rpath/libMoltenVK.dylib (after an SDK loader, so the
validation layer still stacks in development). The suite's SDK stand-in (vk_env) is gone: the
render checks draw on the MoltenVK the package carries. gpu_is_gl() removed; nothing calls it.

ludic-dev test 306/306 with no Vulkan SDK in the environment.
