Provide alternative for cairo_xlib_surface_create on other display outputs

[mmuman]

What happened?

Some conky scripts call cairo_xlib_surface_create to draw, because it is exposed by Lua, which breaks portability to other GUIs.

What should we do about it? Wrap it around some dispatch code?

We could probably add a custom loader for require or override it to always load conky flavor of cairo. (similar issue in sol2)

[Caellian]

Oh, I thought the issue was that require 'cairo' would include system libraries instead of conky ones.

My new understanding of this issue is that cairo_xlib_surface_create doesn't work with Wayland display output.

I'm repurposing this issue as it has been addressed by #1844.

[Caellian]

In future, it would be nice to add some generic function that handles surface creation regardless of currently used display output.
