update_appearance (#55468)

Creates update_name and update_desc
Creates the wrapper proc update_appearance to batch update_name, update_desc, and update_icon together
Less non-icon handling code in update_icon and friends
Signal hooks for things that want to change names and descriptions
99%+ of the changes in this are just from switching everything over to update_appearance from update_icon
