URP TAA implementation leaks accumulation buffers when entering the Play Mode
Reproduction steps:
1. Open the attached Project “TAA_Leak”
2. Open the “Assets/Scenes/Example Scene.unity”
3. Enter and exit the Play Mode multiple times
4. Open Window > Analysis > Memory Profiler
5. Click on the “Capture New Snapshot” and then the “Take Snapshot” buttons
6. Select the generated Snapshot and go to the “Unity Objects” section
7. Write in the search bar “TAA”
8. Observe the number of objects in “RenderTexture”
Expected result: There are no TAA objects in “RenderTexture”
Actual result: Amount of TAA objects in “RenderTexture” increases each time the Play mode is entered
Reproducible with: 2022.2.5f1, 2022.2.17f1, 2023.1.0b14, 2023.2.0a12
Not reproducible with: 2020.3.47f1, 2021.3.24f1, 2022.2.4f1

Note: If the snapshot is taken while Editor is in the Play Mode, after all the steps there should be one object in “RenderTexture”
