…y typed

> Include all necessary information without duplication.

Example 1:

```
private ?ObjectManagerInterface $objectManager;
```
should not require a comment
```
/** @var ObjectManagerInterface|null $objectManager */
```
because all of that information is duplicated.  (Though the nullable is actually harder to read in DocBlock standard.)

Example 2:
```
    public function getWeakMap() : WeakMap
    {
        return $this->weakMap;
    }
```
This method is expressive. It is obvious what it does. It is strictly typed. There is no reason that it should need a DocBlock.

This change no longer requires DocBlock in these cases:

1: member variables that have defined types
2: methods where all parameters have defined types AND method has defined return type (__construct and __destruct won't require return type, since it isn't allowed)

Adding in code to check the namespace of the class/interfaces to see if it is API.
Magento's API code requires method Doc Blocks because it doesn't use Reflection for types.

* Updated unit tests to cover new functionality reguarding when we can safely skip requiring DockBlocks
* Fix MethodArgumentsSniff to work on PHP files without namespaces
