Feature Request Allow support for custom Fallback for Shaders generated by ShaderGraph

Hello

Original post here.

It would be nice to have an option for Fallback support in ShaderGraph (for example "Fallback off", or fallback to another ShaderGraph).

It would be nice to see what is the shader compilation target used for a specific Shader Graph (i assume this is autogenerated based on Nodes/Subgraphs/Target/API used), so one could plan their Fallback/optimize correctly. It might be reasonable to allow user to adjust the shader compilation target manually and not have it auto-generated (id assume this goes hand in hand with the Fallback).
