LibWeb: Begin painting video controls on HTMLVideoElement layout nodes

Browse source 
If the video element has a 'controls' attribute, we now paint some basic
video controls over the video element. If no frame has been decoded yet,
we paint a play button on the center of the element.

If a frame has been decoded, we paint that frame and paint a control bar
on the bottom of the frame. This control bar currently only contains a
play/pause button, depending on the video's playback state. We will only
paint the control bar if the video is paused or hovered.
