[Support] Change SaturatingAdd()/SaturatingMultiply() to use pointer for returning overflow state
Summary:
Improve SaturatingAdd()/SaturatingMultiply() to use bool * to optionally return overflow result.
This should make it clearer that the value is returned at callsites and reduces the size of the implementation.
