LibWeb: Introduce dedicated painting command for borders

Browse source 
Currently, in CPU painter, border painting is implemented by building
a Gfx::Path that is filled by Gfx::AntiAliasingPainter. In the GPU
painter, we will likely want to do something different, and with a
special command, it becomes possible.

Also, by making this change, the CPU executor also benefits because now
we can skip building paths for borders that are out of the viewport.
