LoadRawTextureData takes more time than expected when using TextureCreationFlags.DontUploadUponCreate



Reproduction steps:
1. Open the Superluminal profiler
2. Open the attached "" 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
