Custom surface shaders using emissive Standard lighting does not match Unity Standard shader without the [Gamma] tag
Reproduction steps:
1. Download and open the attached "StandardEmissiveRequiresGammaTag.zip" project
2. Open the "main" scene
3. Observe the Game view
Expected result: "Custom Standard Simple" materials look identical to "Custom Standard Simple [Gamma]" materials
Actual result: "Custom Standard Simple" materials are brighter than the "Custom Standard Simple [Gamma]" materials
Reproducible with: 2019.4.36f1, 2020.3.31f1, 2021.2.15f1, 2022.1.0b11, 2022.2.0a7

Resolution Note:
The provided surface shader is different than Standard.shader because it has [HDR] on the _EmissionColor property.
Adding [HDR] sets the color property to be in linear space by default unless the [Gamma] tag is added in which case it will then go back to being sRGB.
