Description of the changes in your PR

• Migrate the image loading functionality from Picasso to Coil. Picasso has not had a new release for some time, and it has been recommended to move to other libraries. Coil also allows the notification icon loading to be greatly simplified, and it provides default configurations for its memory and disk caches.
• Remove the image indicator toggle from the settings as Coil does not have that functionality. Logging has been enabled instead for debug builds.
• Enable RGB-565 support for low-RAM devices only.
• This change is needed for PR Migrate comment fragments to Jetpack Compose #11060 as it makes use of Coil's Compose functionality.
