This iterates through every field in this InputfieldWrapper and looks for field names that are also present in the given object or array. If present, it uses them to populate the associated Inputfield.
If given an array, it should be an associative with the field 'name' as the keys and
the field 'value' as the array value, i.e.
['field_name' => 'field_value'].
$array = $inputfieldWrapper->populateValues($data);
