LibWeb: Set up initial infrastructure for non-math functions in calc

Browse Source 
There are some non-math functions (such as tree counting functions)
which we should allow within `calc()`s . This commit implements the
initial infrastructure for this.

We don't yet parse any of these non-math functions in
`parse_a_calculation` so there is no functional change.
