Fix #3389. It seems some functionality was left behind when JAMA was eliminated (PR #3260). In particular, it is apparently a known trick to use double negation on boolean values as arguments to functions like SUMPRODUCT.

Fix #3396. Apply same change for booleans in arrays used on either side of mathematical operator.

Treat booleans in arrays as int for mathematical operators as well.

When array operand was neither numeric nor boolean, PhpSpreadsheet had always been evaluating the operand as #NUM!. It will now propagate an error string like #DIV/0!, and treat non-error strings as #VALUE!, consistent with Excel.
