Aliaksandr Kalenik cc447c9c80 LibWeb+WebContent: Move paint recording init into Navigable
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.
