[iOS] Memory increases significantly when a TMP Text component has a lot of text
How to reproduce:
1. Open the attached Project "Test_TMP.zip"
2. Build and Run a Development Build of the Scene "SampleScene" on iOS
3. Open the Memory Profiler (Window -> Analysis -> Memory Profiler)
4. Attach the Memory Profiler to the running Player and Capture a Snapshot
5. In the Player click the "FULL" Button
6. In the Memory Profiler capture another Snapshot
7. Compare the Snapshots
Expected result: barely any additional memory is used
Actual result: memory usage increases by 40-70MB
Reproducible on: 2021.3.40f1, 2022.3.36f1, 6000.0.9f1
Reproduced on:
- iPhone 13 (iOS 15.0)
- iPad Pro (9.7 inch, WiFi) (iOS 14.8)
Notes:
- On macOS, the memory increase is ~6MB
- The json file containing the text takes up 46KB of space

Resolution Note:
After careful consideration, we've decided not to pursue this fix at present. It would require a significant refactoring of TextMesh Pro's architecture, moving from individual component buffers to a centralized service model. Given the scope and potential risks involved, we've determined that this change is too risky for U6 at this time.
