When the type of the Stencil Ref property in the shader is an integer, SRP batching is not broken even if the stencil ref value's differ

Steps to reproduce:
1. Open the attached user's project "StencilTest_6000.zip"
2. Open "test2.unity" Scene
3. Set the Stencil value of "Test_UseSRPBatching_Main" and "Test_UseSRPBatching_Sub materials" to 20
4. Set the Stencil value of "Test_UseSRPBatching_Main 1" and "Test_UseSRPBatching_Sub 1 materials" to 21
5. Open Scene View and observe the rendering
6. Set the _StencilValue type in "UseSRPBatching_Main.shader" and "UseSRPBatching_Sub.shader" to Float
7. The rendering result is different when the type of _StencilValue property is Integer or Float

Expected results: When the type of the Stencil Ref property in the shader is an integer, SRP batching is broken
Actual results: When the type of the Stencil Ref property in the shader is an integer, SRP batching is not broken even if the stencil ref value's differ

Reproducible with: 2021.3.43f1, 2022.3.45f1, 6000.0.18f1
