Shadow casters can't be SRP-batched when they have different UnityPerMaterial values
Reproduction steps:
1. Open the attached project "ShaderGraphSRPBatcher.zip"
2. Enter Play mode
3. Open the Frame Debugger window and enable it
4. Select either of the two "ShadowLoopNewBatcher.Draw" draw calls under "HDRenderPipline::Render Main Camera/ExecuteRenderGraph/RenderShadowMaps"
Expected result: The draws are batched
Actual result: The draws are not batched, a message is displayed:
"Why this draw call can't be batched with the previous one
Objects either have different shadow caster shaders, or have different shader properties / keywords that affect the output of the shadow caster pass"
Reproducible with: 10.9.0 (2020.3.35f1), 12.1.7 (2021.3.4f1), 13.1.8 (2022.1.3f1), 14.0.3 (2022.2.0a15)
Could not test with: 7.7.1 (2019.4.39f1) (Broken assets when downgrading/remaking project)
Reproducible on: macOS 12.0.1 (Intel)
Note: In 2022.2.0a15 the second line of the message is under Batch Cause
