Includes in the rofi code base are a complete mess; there are many
needless includes and many files rely on transitive includes.
I used include-what-you-use tool to find them. There are much more,
I cherry picked only suggestions relevant to the goal - allow building
rofi without XCB dependencies.
This doesn't break X11 support and it can be upstreamed (after rebasing
and removing changes in wayland-stuff).
