GLTF Embed as Uncompressed will still extract textures when importing. (regression)

### Tested versions

4.4beta

### System information

windows 10

### Issue description

When the Project Import settings for GLTF Embedded Image Handling is set to Embed as Uncompressed. It will still extract the images and not keep them embedded! This use to work in 4.3 but not in 4.4!

### Steps to reproduce

Set the project settings and import a gltf. Example gltf is provided (uses embedded texture):

### Minimal reproduction project (MRP)

[test-4.4.zip](https://github.com/user-attachments/files/18914454/test-4.4.zip)

Start by opening the attached minimal reproduction project and importing the provided embedded-texture GLTF with Embedded Image Handling set to Embed as Uncompressed. Compare the 4.4 behavior with the reported 4.3 behavior; done means the texture remains embedded instead of being extracted.
