Materials do not get batched when GPU Instancing is enabled and Texture2dArray is used
How to reproduce:
1. Open attached project "GPUInstancing.zip" and scene "SampleScene"
2. Enter Playmode
3. Observe Scene view -> Stats -> Batches
Expected result: the Batches is low (due to materials getting batched)
Actual result: the Batches number is around 680-750 (the number is inconsistent)
Reproducible with: 2017.4.33f1, 2018.4.12f1, 2019.2.10f1, 2019.3.0b9, 2020.1.0a9

Resolution Note (2020.2.X):
Automatic instancing doesn't allow having non-instanced properties in the MaterialPropertyBlock object, including textures. To set a shared texture property for all instances, you can set it on the material directly, or use Graphics.DrawMeshInstanced instead.
