Support for Picture-in-Picture (PiP) and In-App Call Minimization in iOS SDK

We request support for enhanced video call multitasking capabilities in the CometChat iOS SDK. Specifically, this includes:

1. Native integration with Apple’s AVPictureInPictureController to enable system-level Picture-in-Picture (PiP), allowing users to continue video calls in a floating window while using other apps.

2. A built-in feature or UI component to minimize an ongoing call into a draggable floating view within the app, enabling users to navigate across different screens without disconnecting the call.

These features would significantly improve the user experience by enabling seamless multitasking during video calls and aligning with modern iOS app behavior.
