LibWeb: Make cell percentage widths relative to table

Browse source 
Cell percentage widths are relative to table width, not containing
block width. If the table width is auto, there isn't a normative
specification, only a brief mention that the user agent should try to
meet it.

As a starting point, we increase the width of the table such that it's
sufficient to cover min-width of cells with a percentage width. This
matches the behavior of other browsers, at least for simple cases.
