Andreas Kling 5069d380a8 LibWeb: Let Element cache its list of classes ...

Instead of string splitting every time you call Element::has_class(),
we now split the "class" attribute value when it changes, and cache
the individual classes as FlyStrings in Element::m_classes.

This makes has_class() significantly faster and moves the pain point
of selector matching somewhere else.
