fix: replace associated object with current TTD tracker

[philprime]

📜 Description

• Uses the currentTTDTracker instead of an associated object

💡 Motivation and Context

We had a an edge case reported where a view controller was dismissed, and in the completion handler the methods viewDidLoad() and viewDidLayoutSubviews() were called. This methods were swizzled and triggered a TTID report.

As the view controller was already being deallocated, a race-condition occurred and the objc_getAssociatedObject accessed a memory with "random" objects instead, leading to an SDK crash.

Here's a link to the Apple Documentation mentioning that view life cycle methods should not be invoked directly.

Closes #5087

💚 How did you test it?
