Decouple `glfw` from `vulkan`

Currently glfw has a dependency on vulkan module, because vulkan-related part in glfw3native.h uses some definitions from Vulkan registry. But this can be avoided somehow.

The situation is more complicated than we've expected. Maybe we need an extra package for handing the interaction between glfw and vulkan. (For example, an glfw-vulkan adaption layer). For now let's just keep the situation as-is.
