Generates a SPARQL function call from a function name and argument expressions.
The generic escape hatch for SPARQL functions without a dedicated builder (str,
datatype, …): renders fn(arg, …) with the arguments comma-joined. Empty arguments, such as
those produced by nil, are dropped first. The name is emitted verbatim, so the caller upholds
the lowercase generated-token convention.
