WindowServer+LibGUI: Yank out window-global opacity

Browse source 
From what I can tell, this facility was added to WSWindow/GWindow in
2019 in 9b71307. I only found a single place in the codebase still using
this facility: `WindowServer::Menu::start_activation_animation()`. A
subtle fade-out animation that happens when a menu item is selected, and
the menu disappears.
I think our compositing facilities have improved enough to make this
facility redundant. The remaining use mentioned above was ported to just
directly blit the fade-out animation instead of requesting it from
WindowServer.
