LibWeb: Don't tolerate unit-less lengths (except 0) in standards mode

Browse source 
"width: 500" is not a valid CSS property in standards mode and should
be ignored.

To plumb the quirks-mode flag into CSS parsing, this patch adds a new
CSS::ParsingContext object that must be passed to the CSS parser.
Currently it only allows you to check the quirks-mode flag. In the
future it will be a good place to put additional information needed
for things like relative URL resolution, etc.

This narrows <div class=parser> on ACID2 to the correct width. :^)
