[Crash] Default Player crash with MTAudioProcessingTapCallbacks

[danielebogo]

Related to #1711

An attempt to fix the crashes related to MTAudioProcessingTapCallbacks.

As a tap can not be synchronously stopped, I suspect we try to access the unretained instance already deallocated.

This solution introduces basically 3 things:

• An AudioProcessingTapProxy which wraps as weak the reference to the current player
• When the MTAudioProcessingTapCallbacks is created, the clientInfo is now an UnsafeMutableRawPointer created with the retained instance of the proxy
• We now implement the finalize closure where we release the previously retained tap instance

To test

• CI must be 🟢
• 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
   • Switch the FF off to check everything still works as before

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.

Can we encapsulate the code bellow to method and used on all places above?
Something like: getPlayerFromTap(_) -> DefaultPlayer

[SergioEstevao]

Tested this on device and it's working correctly, just left a suggestion for code improvement.
