Errors are thrown when an empty texture is selected in Object Picker on DX12

Steps to reproduce:

1. Create and open a new project
2. Change the Graphics API to Direct3D12 in 'Edit -> Project Settings -> Player'
3. Create a new Script with a line "[SerializeField] private Object obj;" in it
4. Instantiate the Script in Hierarchy
5. Import TextMeshPro Examples and Extras
6. Open the Object Picker in the Script instance
7. Select any one "Font Texture" from the list in Object Picker (it's of size 0B and has the resolution of 0x0)
8. Observe the Console

Actual results: "d3d12: Attempting to bind a NULL or empty texture.  Perhaps the texture contains no image data or has an invalid size." is thrown on each Object Picker window refresh

Expected results: Nothing or a warning is thrown in the Console

Reproducible with versions: 6000.0.0f1, 6000.0.77f1, 6000.3.17f1, 6000.4.11f1, 6000.5.0b12, 6000.6.0a7

Tested on (OS): Windows 11 Pro (25H2)

Notes:

• Reproduction is not always consistent; it's not clear why certain empty textures fail to be parsed, while others do not
• Not reproducible with Vulkan, DX11
