Move the aliasing of promoted function pointers to the function pointer lookup collection, because non-global function alias symbols are not available in separately compiled object file. Add public aliased Vulkan extension functions that were promoted to 1.1 to the public symbols that are hidden when MVK_HIDE_VULKAN_SYMBOLS is enabled. Add functions from the private VK_MVK_moltenvk extension that depend on Vulkan object handles to the public symbols that are hidden when MVK_HIDE_VULKAN_SYMBOLS is enabled, to discourage their use by apps that are using the Vulkan Loader and Layers, because they are not supported by the Vulkan Loader and Layers. Update VK_MVK_MOLTENVK_SPEC_VERSION to version 33.
