Terrain not visible when loaded from Asset Bundle and has Draw Instanced enabled
How to reproduce:
1. Open a project from OC ("AssetBundleTerrain.zip")
2. Open SampleScene
3. Press Play
Notice it does load a scene with a terrain.
4. Assets > Build AssetBundles
5. Build the standalone application in "bin" folder
6. Run it
Notice, it does not load a terrain anymore, even though it's in the Asset Bundle and in the Scene.
Expected result: Terrain is visible
Actual result: Terrain is not visible

Resolution Note (fix version 2020.1):
The behavior of how Always Included Shaders works is that all Variants will be built for those shaders, Instancing variants however will be built based on Graphics Settings Instancing Stripping. In this case, since the terrain is in a bundle, but the shaders are in the build, the terrain data cannot influence how the shaders are built. This is a known limitation that we are not fixing.
If you take the sample project provided, and remove the terrain shaders from the Always Included Shaders list in Graphics Settings (or reset Graphics Settings), rebuild bundles and player, everything, including instancing, works correctly due to this fix.
