wayland: Phase 16 — handle request_maximize, request_fullscreen, request_minimize, set_app_id 

Wire xdg-toplevel event listeners for the remaining lifecycle events:
- request_maximize: toggles wMaximizeWindow / wUnmaximizeWindow
- request_fullscreen: calls wFullscreenWindow
- request_minimize: calls wIconifyWindow
- set_app_id: updates wwin->wm_class when the app changes its app_id

Include actions.h and xinerama.h for the WM action function declarations.
