LibWeb: Modernize handling of the CSS flex-basis property

Browse source 
Instead of a custom struct, use an AK::Variant for flex-basis.
A flex-basis is either `content` or a CSS size value, so we don't need
anything custom for that.

By using a CSS size, we also avoid having to convert in and out of size
in various places, simplifying the code.

This finally gets rid of the "Unsupported main size for flex-basis"
debug spam. :^)
