Add Controller to get asyncUpload signatures

Added new files for handling asynchronous file uploads in ChillDocStoreBundle. The new files include a controller for generating temporary URLs (AsyncUploadController.php), a security authorization file (AsyncUploadVoter.php), and a corresponding test file (AsyncUploadControllerTest.php). These implementations permit asynchronous uploads via POST, GET, and HEAD methods while maintaining security protocols.
