Breaking: #72400 - Removed deprecated IconUtility and SpriteManager¶
See Issue #72400
Removed deprecated IconUtility class completely. All SpriteManager related code has been removed from the core.
The Install Tool option
BE/spriteIconGenerator_handler has no effect anymore.
Bootstrap::initializeSpriteManager() has been removed.
Using the static class IconUtility or the SpriteManager will result in a fatal error.
Instances which use custom calls to one of the above mentioned classes.
Use the new introduced IconAPI that is available since 7LTS.
