fix: Simulator Crash for Non-DRM Video Playback

- Currently, we initialize the AVContentKeySession even for non-DRM videos. This causes issues when attempting to play non-DRM videos in the simulator, as the content key session cannot be initialized on the simulator. Consequently, this results in a crash during playback.
- This is fixed by initialization AVContentKeySession only when the Asset is DRM-encrypted, so the app won't crash while playing non-DRM content in Simulator.
