Changing PlayerSettings.GraphicsAPI reimports all textures regardless of their compression settings

Asset Importers


To reproduce:
1. Create a new Unity project
2. Add a texture to the Assets folder (you can use the one that is attached to this case)
3. In the Inspector, set texture 'Format' to "RGBA 32 bit"
4. In "Project Settings/Player/Other Player", uncheck the 'Auto Graphics API for Windows'
5. Add or remove "Direct3D12" (or any other) Graphics API for the Windows list

Actual result: The texture gets recompiled (as in the attached video).
Expected result: The texture does not get recompiled.

Reproducible with: 2019.3.0a10, 2019.3.0b6, 2020.1.0a8
