[ComputeBuffer] .mdb with .dll causes Compute Buffer to become unbound
Steps to reproduce:
1. Open the attached project
2. In the Project view, drop the Shader 'ReadBuffer' onto 'Material'
3. Drop 'Material' onto 'Cube' in the Hierarchy
4. Press Play and notice that the cube is green
5. Defocus the editor window, notice that the cube changes to black
6. Stop the scene
7. Delete either 'TestDll.dll' or 'TestDll.dll.mdb' and Play
8. Notice that the cube no longer changes to black
Workaround: Resetting the buffer in Update (Toggle 'Enable Fix' in 'GameObject')
Expected: Buffer stays the same and cube doesn't change
Reproduced with: 5.4.0b15, 5.3.4p3, 5.2.3p3

- "DateTime.Now" in the UK timezone does not adjust when the British Summer Time is active
- "Unsupported source texture format (7) in ComputeNextMipLevel" error is shown and the texture atlas is corrupted when the texture format "RGB Compressed ETC2 4bits" is selected
- The label that uses data binding is no longer updated at runtime when `INotifyBindablePropertyChanged` reloads updates of the VisualTreeAsset in UIDocument
- HDRP Graphics "High Quality Line Rendering" is missing a documentation link
- HDRP Graphics "Screen Space Global Illumination" has a link to a wrong documentation
Resolution Note:
Reloading any asset results in materials being Awoken, which clears the non-serialized state like ComputeBuffer references.
We expect that script code has to ensure it is assigned correctly every frame or after asset import changes have occurred.
