LoadRawTextureData takes more time than expected when using TextureCreationFlags.DontUploadUponCreate
Reproduction steps:
1. Open the Superluminal profiler
2. Open the attached "repro_IN-40868.zip" project
3. Start profiling the "Unity.exe" process in the Superluminal profiler
4. Enter the Play Mode in the Unity Editor
5. After a few seconds, stop the Play Mode
6. Stop the profiling in the Superluminal profiler
7. Observe the profiling data
Expected result: no time is spent on Texture2D::UnshareTextureData during LoadRawTextureData, because TextureCreationFlags.DontUploadUponCreate is in use so the TextureData should not be referenced by the upload.
Actual result: the data upload is skipped, but Texture2D::UnshareTextureData still takes longer than expected (RefCount is not 1).
Reproduced with: 2022.2.20f1, 2023.1.0b17, 2023.2.0a16
Could not test with: 2020.3.48f1, 2021.3.25f1 (does not have TextureCreationFlags.DontUploadUponCreate included in the code)
Reproducible on: Windows 10
Note: Reproducible in builds
