- Add Volk repo to fetchDependencies script and ExternalRevisions/Volk_repo_revision file. - Cube.xcodeproj modify header paths, use of Volk, and remove old and unused files. - Update Demos/README.md to explain that Volk requires MoltenVK be built with build setting MVK_HIDE_VULKAN_SYMBOLS enabled. - MVKInstance support aliasing function name in one extension to a function in another extension, to allow MVK_HIDE_VULKAN_SYMBOLS to work with extensions promoted to another extension, but not to core, and remove additional duplicate functions that were promoted to 1.3, but were breaking use of MVK_HIDE_VULKAN_SYMBOLS.
