[Mobile] [Texture] Sprite corrupted or invisible in Atlas using certain dimension RGB(A) Compressed 5x5 or 10x10 block sprites



Reproduction steps:
1. Open project in ""
2. Set the platform to iOS (File -> Build Settings)
3. In the Project window select Sprite Atlas
4. In the Inspector window, press "Pack Preview"
5. Inspect the preview

Expected result: There are 2 Sprites packed, a green 128x128 and a red 130x130 square, both are clean, without artifacts
Actual result: Red 130x130 square sprite is corrupted (130x130 dimension is the culprit)

Reproducible with: 2021.1.0a2, 2021.1.4f1, 2021.2.0a13 (IMPORTANT TO READ NOTES BELOW)
Not reproducible with: 2018.4.34f1, 2019.4.24f1, 2020.3.5f1, 2021.1.0a1

Reproducible on Android and iOS platforms

1. In versions 2021.1.0a2 - 2021.1.0a5 the 130x130 sprite is invisible and starting with 2021.1.0a6 it becomes corrupted, I am not sure if this is the same issue
2. This happens with RGB(A) Compressed ASTC, or RGB(A) Compressed ASTC HDR sprites that are 5x5 or 10x10, the corruptions are different
