Constant buffers are redundantly uploaded when consecutive compute dispatches are executed on DirectX11

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scenes/SampleScene.unity” Scene
3. Right-click on the Game view tab and select “Load RenderDoc“
4. Enter the Play mode
5. Select the “Camera“ icon at the top of the Game view to take a RenderDoc Capture
6. Load Capture in RenderDoc
7. In the Event Browser, filter by term “ExecuteSetPositionsBuffer“
8. Expand “UIR.DrawChain“
9. Expand “SceneCamera.Render“
10. Select “ExecuteSetPositionsBuffer“
11. Remove the search term and press the “Enter” key
12. Expand “ExecuteSetPositionsBuffer“
13. Observe the first and second dispatch

Expected result: The second Map/Unmap/CSSetConstantBuffers sequence is skipped
Actual result: CSConstantBuffer-0-16 is being Map/Unmap twice between two consecutive Dispatch calls

Reproducible with: 6000.0.60f1, 6000.2.8f1, 6000.3.0b6, 6000.4.0a2

Reproducible on:
Play Mode

Could not test on:
Windows Standalone Player (Assets\Scripts\MeshSaverEditor.cs(7,40): error CS0246: The type or namespace name 'MenuCommand' could not be found)

Testing environment: Windows 10 Enterprise 21H2
Not reproducible on: No other environment tested
