Add extended reasons tips to param out errors

[thg2k]

This adds the very useful tips on complex types also to param-out.

Please carefully review the correctness, I assume that isSuperTypeOf and acceptsWithReason are equivalent.

Also not sure how to set the strictness parameter, as it is a param-out it should not be affected by the strict types declare.

Before:

 ------ ----------------------------------------------------------------------------------------------------------------------------
  Line   case2.php
 ------ ----------------------------------------------------------------------------------------------------------------------------
  8      Parameter &$foo by-ref type of function foo() expects array{a: int, b: int, c: string}, array{a: int, b: int, c: 5} given.
           parameterByRef.type
          You can change the parameter out type with @param-out PHPDoc tag.
 ------ ----------------------------------------------------------------------------------------------------------------------------

After:

 ------ ----------------------------------------------------------------------------------------------------------------------------
  Line   case2.php
 ------ ----------------------------------------------------------------------------------------------------------------------------
  8      Parameter &$foo by-ref type of function foo() expects array{a: int, b: int, c: string}, array{a: int, b: int, c: 5} given.
           parameterByRef.type
          Offset 'c' (string) does not accept type int.
          You can change the parameter out type with @param-out PHPDoc tag.
