jeanmichel dignard 0f92c82ddf Asset Thumbnails
- Moved the thumbnail dirtying from FThumbnailPool to UThumbnailManager as it only needs to happen once per thumbnail, not once per pool.
- Prevent trying to dirty thumbnails in the asset package for generic thumbnails that don't get rendered.
- Prevent the reference viewer CDO from creating a thumbnail pool as it happens too early and isn't needed.

Saves around 20 seconds when entering PIE.
