Motion vectors are calculated incorrectly when using TAA
Reproduction steps:
1. Open the "terra" project
2. Open the “Assets/TerrainDemoScene_HDRP/Scenes/TerrainDemoScene.unity” Scene
3. In the Hierarchy Window select “Main Camera” GameObject
4. Observe that TAA is selected under the “Rendering” Component in the “Post Anti-aliasing” Property
5. Observe grass in the Scene View
Expected results: Grass is clearly visible
Actual results: Grass flickers
Reproducible with: 2022.2.9f1, 2023.1.0b6, 2023.2.0a4
Could not test with: 2020.3.45f1 (Packages required are not available for this version), 2021.3.20f1 (error CS0246: The type or namespace name 'DetailBrushRepresentation' could not be found (are you missing a using directive or an assembly reference?))
Reproduced on: Intel MacOS 13.1
Note: The issue can be seen more vividly when entering the Play Mode and viewing the Game View

Resolution Note:
A preivous fix have been done to fix the very blurry grass. The remaining part
require proper handling of motion vectors for terrain detail meshes and is a feature request, not a bug. For now due to limited resources we don't know when this part could be fixed. - We track the work as a feature request to support motion vector on detail meshes
