[Nette] Add ContextGetByTypeToConstructorInjectionRector

[TomasVotruba]

Do you want to get rid of $this->context?

 class SomeClass
 {
     /**
      * @var \Nette\DI\Container
      */
     private $context;

+    /**
+     * @var SomeTypeToInject
+     */
+    private $someTypeToInject;
+
+    public function __construct(SomeTypeToInject $someTypeToInject)
+    {
+        $this->someTypeToInject = $someTypeToInject;
+    }
+
     public function run()
     {
-        $someTypeToInject = $this->context->getByType(SomeTypeToInject::class);
+        $someTypeToInject = $this->someTypeToInject;
     }
 }
