Subject: Hide "Normal Map" import option when using lossless compression on
 Texture

This pull request resolves an issue where images being imported with lossless compression allowed you to select a normal map, but the normal map only applies if you're using VRAM compression. Thereby making it redundant to appear when using lossless compression. This pull request hides the normal map option when lossless compression is selected.

Resolves: #59435
