[CodeQuality] Re-use existing #[Required] method in ControllerMethodInjectionToConstructorRector

[TomasVotruba]

When a controller already has an injection method – one with #[Required], or named autowire*() – the rule now appends to it, instead of creating a second autowire<ShortClassName>() method next to it.

 final class ReUseExistingRequiredMethod extends ParentControllerWithConstructor
 {
     private TranslatorInterface $translator;
+    private \Psr\Log\LoggerInterface $logger;

     #[Required]
-    public function autowireTranslator(TranslatorInterface $translator): void
+    public function autowireTranslator(TranslatorInterface $translator, \Psr\Log\LoggerInterface $logger): void
     {
         $this->translator = $translator;
+        $this->logger = $logger;
     }

     #[Route('/example', name: 'example')]
-    public function example(LoggerInterface $logger)
+    public function example()
     {
-        $logger->log('level', $this->translator->trans('value'));
+        $this->logger->log('level', $this->translator->trans('value'));
     }
 }

Only public, non-static methods with a body are considered. If none is found, a fresh autowire<ShortClassName>() method is created as before.
