"Shader warning in 'Hidden/HDRP/DownsampleDepth'" warnings are thrown after building a project

Unity: SRP Foundation

Fixed

2022.3.X

2022.3.49f1 onwards

Steps to reproduce:
1. Create a new project with Cinematic Studio Sample or High Definition 3D Sample templates
2. Build And Run
3. Observe the Console

Actual results: "Shader warning in 'Hidden/HDRP/DownsampleDepth': implicit truncation of vector type at Packages/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/DownsampleDepth.shader(81) (on metal)" warnings are thrown
Expected results: No errors or warnings are thrown

NOTE:
selecting DownsampleDepth.shader in the project with hdrp, if you do "compile and show code" for d3d - same warning are generated (so the only difference is perhaps that xr path with texture arrays is not active by default on d3d or something along the lines). This is something in hlsl code being fed to fxc

Reproducible with versions: 2022.3.491, 2022.3.53f1
Not reproducible with versions: 2021.3.45f1, 2022.3.48f1, 6000.0.23f1{}

Tested on (OS): macOS Sonoma 14.5 (Intel)
