LibWeb: Schedule repainting from EventLoop::process()

Browse source 
In this change, updating layout and painting are moved to the EventLoop
processing steps. This modification allows the addition of resize
observation dispatching that needs to happen in event loop processing
steps and must occur in the following order relative to layout and
painting:

1. Update layout.
2. Gather and broadcast resize observations.
3. Paint.
