New package: glfw-wayland-3.3
https://github.com/void-linux/void-packages/pull/13918

Description:
This provides a wayland version of glfw, like other distros do. The devel files and stuff are shared, so this only installs the library. (glfw does not allow both choices at runtime yet, so a separate package is the only way to do it)
