separate GLX and vulkan feature into own lib

Hi

Why vulkan and GLX is stored in the same lib instead of separate own lib?

i want test the new nvidia vulkan driver (https://developer.nvidia.com/vulkan-driver) and the opengl 4.6 features (https://developer.nvidia.com/opengl-driver) but i cant mix these new features with the actual driver (opengl 4.6 and vulkan is 381.xx.xx branch, and the actual driver is 384.xx(69))

greetings
