Browser+LibWeb: Add an Element size preview widget to inspector

Browse source 
This Adds an element size preview widget to the inspector widget
in a new tab. This functions similar to chrome and firefox and
shows the margin, border, padding, and content size of the selected
element in the inspector.

The colors for the size preview widget are taken from the chrome
browser.
