Pass the reference of the proxy if needed

[danielebogo]

Ref. #2521

This PR should fix the crash in the Audio callback. Compared to the previous fix, we missed few spot where the unretained pointer was injected directly into the callback. This was causing a crash as the expected opaque type should always be the proxy and not the player.

To test

• CI must be 🟢
• Run this branch and play an episode with the volume boost on
• Confirm the app won't crash
• Try to play and change episodes while playing
• When the system decides to finalize the tap you will see 2 logs in this order:

1. The log from the finalize closure: [AudioProcessingTapProxy] Finalize tap: <MTAudioProcessingTap 0x6000030513b0> Retain count 3 Created with i/f/p/u/t callbacks = {0x10aa14448/0x10aa14600/0x10aa149b4/0x10aa14d08/0x10aa15330} flags = 0x1
2. The log from the proxy deinit: [AudioProcessingTapProxy] Deinit proxy

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.
