Module printer 

Printing of MirScalarExpr in the syntax accepted by the parser.

Unlike the EXPLAIN printer, which renders function variants by their SQL name (losing the exact variant, e.g. + for every add function), this printer renders exact variants by their canonical name. Parsing the output reconstructs the original expression. Test tooling uses this to generate parser inputs.
