LibCore+Ladybird: Add EventLoopManager interface for persistent state
Things such as timers and notifiers aren't specific to one instance of Core::EventLoop, so let's not tie them down to EventLoopImplementation. Instead, move those APIs + signals & a few other things to a new EventLoopManager interface. EventLoopManager also knows how to create a new EventLoopImplementation object.
