How to reproduce:
1. Create a new VFX (I noticed it happening in URP, HDRP hadn't thrown a warning from what I tested)
2. Observe console
Actual result: Shader warning in '[New VFX 1] [System] OutputUpdate': Extra space between '\' and newline. at kernel CSMain at VFXCommon.hlsl(217) is thrown to the console
