feat: flip binary operator check if failed

if vm.runOperator fails try again with flipped arguments
this emulates how lua checks the binary metaevents in which
if there is no corresponding binary metaevent for the left
operand it checks the right operand instead. This also works
when both operands are tables.

This change affects:
- __add
- __sub
- __mul
- __div
- __idiv
- __mod
- __pow
- __concat
- __band
- __bor
- __bxor
- __shl
- __shr
