This refactoring makes WebContent less aware of LibWeb internals. The code that initializes paint recording commands now resides in `Navigable::paint()`. Additionally, we no longer need to reuse PaintContext across iframes, allowing us to avoid saving and restoring its state before recursing into an iframe.
