Refactor cage into separate source files This makes Cage much easier to maintain. Not only is it easier where to look and to maintain a mental model of the code, there is also more encapsulation, better abstractions and better extendability.

Add XWayland support With Cage becoming more popular since its mention on Phoronix and therefore getting more use-cases than just my own project, add XWayland support. The refactoring of 2cf40f7 makes this much easier. Note that this is a no-cost addition for those of us not using XWayland as it is a compile-time option that needs to be explicitly enabled by adding `-Dxwayland=true` to your meson command.

Properly track mapping and unmapping We shouldn't render a window before it is mapped (obviously), but we render all windows in the view list. Hence, only insert the window once it is mapped. We could run into the case where a window is destroyed without being in the window list, so we now track unmapping again and remove windows from the list when they get unmapped.
