[Vulkan] Adreno 630/640 generates corrupted mipmaps when height of the texture is power of 2 + 1

Terrain

-

To reproduce:
1. Download and open 1159644_smallerRepro.zip project
2. Build and run project on an Android device with Adreno 630

Expected result: Plane is rendered like in the editor
Actual result: Plane texture is corrupted

Note: Reproduces when texture height is a number power of 2 +1, for example 513, 1025 etc. so if texture size is 513x513 - it reproduces. If 513x512 - doesnt. If the height is any other number - it does not reproduce neither.

  1. Resolution Note (2019.3.X):

    This issue is caused by Adreno 630 and 640 drivers. When texture has size of 513x513 generated mipmaps are corrupted so objects with lower level of detail are using corrupted mipmaps hence the originally described artifacts appear.
