[Toolkit feature]: Asset Replacement Texture preview viewer alpha on/off and file picker thumbnail view request

What is the context of the feature/improvement?

In the Toolkit Assets Replacements texture viewer (the magnifier icon), if the texture doesn't use an alpha channel it will only show a blank texture which can make it difficult to identify textures replacement.

For my project some of the in-game monitors show animations using individual textures with unused alpha channels and minor variations between them making it difficult to identify texture replacements. As a work around open the captured texture in file explorer then view in a image viewer which is slower.

Please describe the feature/improvement?

Checkbox to turn on/off alpha channel view when clicking the magnifier view and thumbnail view in file picker.
