[ARCore] [Android] Memory leak in XR application when using AROcclusionManager component

Package: ARCore

-

How to reproduce:
1. Open the attached project "1379235"
2. Change platform to Android
3. Open Build Settings and enable Development Build
4. Build and Run on Android device
5. Open Memory Profiler and connect to the Android device
6. In the Android app, go to Depth > Simple Occlusion and make sure the camera is not covered (the screen should not be black)
7. In the Memory Profiler window, press 'Capture' to take Snapshot
8. After 2 minutes, press 'Capture' again and compare both snapshots

Expected result: The memory went from ~460 MB to 520 MB
Actual result: The memory went from ~460 MB to 700 MB

Reproducible with: 4.2.0-pre.7 (2020.3.23f1), 4.2.1 (2020.3.23f1, 2021.2.5f1, 2022.1.0b1)
Not reproducible with: 4.1.3 (2019.4.33f1), 4.2.0-pre.5 (2020.3.23f1)

Notes:
- If the issue does not reproduce, the memory always stays at ~520 MB when testing for a longer time
- If the issue reproduces, the memory can go over 1 GB when testing ~4 minutes
- Does not reproduce on iOS
- If the camera is covered (black screen), it's harder to reproduce because the memory rises at significantly lower speeds (can be under 100 MB jump in 10 minutes)
