native/linux: Use macro to reduce boilerplate

[bolphen]

This avoids writing the same function name 5 times in 3 different places.

I didn't convert the egl file yet. Did the egl file as well. The gl one seems to have its own macro.

The macro itself is inspired by the dlib crate, but I made it less verbose with the ... syntax. I'm also open to other suggestions.

Once this got merged I'll start submitting the PRs for the Wayland backend :)

Great work! 👍

I am little bit on the fence about ..., but can't really build a strong opinion on this. Intuitively explicit static/function etc lists would be easier to read, but not by much and we only use the macro a handful of times. I do not have very strong opinion on this tbh, very excited to see how it will turn out with wayland!

Cool!

Yeah worst case we could always change it in the future since it's not exposed to the user.

The Wayland backend is pretty much on a par with X11 now :) I'll open a PR
