MDL-36733 qtype_calculated: Wildcards in calculated question hints

Browse Source 
The placeholders for the hints are properly replaced by this change and any formulas present are replaced.

The validation is performed by the existing function qtype_calculated_find_formula_errors(),
which is called by the calculate() function,
which in turn is called by the variable substituter "vs" using the replace_expressions_in_text() function.

vs -> replace_expressions_in_text() -> calculate() -> qtype_calculated_find_formula_errors().
