Wayland: Move window related code to window module

Browse Source 
The Wayland backend was the only one where half the window and input
related code was in the init module.  As those bits want to share more
utility code with the window module, the interface between them grows.

To prevent that, this gathers nearly all window and input related code
into the window module.
