Allow \stdClass for input types

[adam1658]

Allow \stdClass in GraphQL\Util\Value::coerceValue. \stdClass will be cast to an associative array, and the coerced value will still be an associative array.

Useful for when you want to parse incoming variables JSON with \stdClass (for example, if you have custom scalars that have this requirement, but cannot distinguish between scalars and inputs at the variables level).

Note that the variables map is still required to be an associative array - one way that users can parse variables JSON in this way is to parse in \stdClass mode, then cast the map to an array:

$variables = (array)json_decode('{"a": {}, "b": []}', false);
var_dump($variables);
/* array(2) {
  ["a"]=>
  object(stdClass)#1 (0) {
  }
  ["b"]=>
  array(0) {
  }
}
*/

Fixes #534.

Please let me know if the implementation, tests or docs changes are incorrect or lacking.

Thanks,
Adam
