LibWeb: Add temporary hack for line-height: calc(...)

Browse source 
At the moment, we can't resolve CSS calc() values without having a
LayoutNode. The new StyleProperties::line_height() overload was trying
to do exactly that, which led to an assertion.

This patch makes `line-height: calc(...)` behave the same as
`line-height: normal` for now and adds a FIXME.
