Sam Atkins 35f64af3a4 LibWeb: Implement CalculationResult type for calc() results ...

calc() sub-expressions can return a variety of different types, which
then can be combined using the basic arithmetic operators. This class
should make that easier to deal with, instead of having to handle all
the possible combinations at each call site. :^)

We take the Layout::Node as a pointer not a reference, since later we'll
need to call these functions when resolving to `<number>` or `<integer>`
which don't use those, and we don't want to force users to pass them in
unnecessarily.
