Tests added for mixed type arithmetic operations #25671

### Changes
* added accuracy tests for mixed type arithmetic operations
    _Note: div-by-zero values are removed from checking since the result is implementation-defined in common case_
* added perf tests for the same cases
* fixed a typo in `getMulExtTab()` function that lead to dead code
