meson: Move -Dvulkan-drivers handling higher in the file

The window-system auto-detection code (specifically for glx) relies on
with_any_vk being available.  This fixes the Vulkan-only build.  Also,
this puts it up near the handling of -Ddri-drivers and -Dgallium-drivers
which seems to make a bit more sense.
