"Does not contain a definition" error for texture.imageContentsHash when building
To reproduce:
1. Open attached Unity project "Unity201703BUG.zip"
2. Inspect "TestTexture" script in the Assets folder
3. Build and run the project
4. Inspect console
Result: "Type 'UnityEngine.Texture' does not contain a definition for 'imageContentsHash' and no extension method..." error, even though there was no compilation error and testing in play mode shows hash value of the texture correctly displayed in the console.
Note: "TestTexture" is not even used in the scene
Note: prior to 2017.3.0b4 the same error would not let you enter play mode, now it only affects build.
Reproduced on: 5.6.5f1, 2017.1.2p4, 2017.2.1p1, 2017.3.0p1, 2018.1.0b1

Issue was resolved and marked "By Design" but there should be additional explanation here:
Texture.imageContentsHash is only meant to work in the Editor because the "consumer" of that parameter is the Editor, not user code (at least not primarily). The documentation isn't very clear on this - it only mentions that it's Editor-only at the end of a paragraph in the middle of the documentation for the parameter. That should really be called out in the short description of the parameter that appears on any page for children of the Texture class.
