Actually sdk-1.2.154.1 for Vulkan-Loader. glslang is updated to bacaef3237c515e40d1a24722be48c0a0b30f75f which is the known-good version for Vulkan-ValidationLayers 1.2.154.0. COPYRIGHT.txt was synced with the current version of the glslang LICENSE.txt, and `glslang/register_types.cpp` now uses the upstream definition for its default builtin resource instead of hardcoding it.
