ShaderVariant throws 'ArgumentException: shader pass type 0 does not have a shader snippet' when using AssetBundle

When a shader is part of an asset bundle, there is not enough information for the Editor to do all the checks it normally does (the source asset is missing in this case). It's best to create those variant collections in the Editor as assets, and not build them at player runtime.

Reproduction steps:
1. Open the attached 'TestShaderVariant' project
2. Open the 'SampleScene'
3. Go to the 'Window -> Asset Management -> Addressables'
4. 'Build -> Clean Build -> All'
5. 'Build -> New Build -> Default Build Script'
6. 'Play Mode Script -> Use Existing Build'
7. Enter Play mode

Expected result: No errors are in the Console
Actual result: 'ArgumentException: shader Unlit/NewUnlitShader pass type 0 does not have a shader snippet' is in the Console

Reproducible with: 2019.4.36f1, 2020.3.30f1, 2021.2.14f1, 2022.1.0b13, 2022.2.0a8
