[TextureCompression] Using "Graphics.CopyTexture" or "SetPixelData" with "PVRTC" Texture Array as the destination will fail on 3 lowest Mipmap levels
How to reproduce:
1. Open project "PVRTC.zip"
2. Open Main Scene (Assets > Scenes > Main)
3. Open a Console window and enter the Play Mode
4. Observe the Console window
Expected result: "Mip 8" size is smaller than "Mip 7"
Actual result: "Mip 8" and "Mip 7" have the same size 32
Reproducible with: 2020.3.29f1, 2021.2.12f1, 2022.1.0b8, 2022.2.0a5
Could not test with: 2019.4.36f1 (Errors after downgrade)
Notes:
- From 2022.1.0a13 no errors appeared in the Console but the bug still reproduces
- Not reproducible with other formats

Resolution Note (fix version 2022.2.0a9):
It's correct that mip 8 is equal size as mip 7. The minimum size for this PVRTC format is 32 bytes. But the exception should not be thrown. It is fixed starting from 2022.1. Backports are under way.
