ACMS-4080 – [9010] Refactor asset thumbnail handling to rely on remote images whenever possible
With these changes the asset's alternate preview set in Widen appears in all contexts when a media item of Drupal is being displayed as a thumbnail. This happens through the shift over relying on embed codes (alternate-supported) instead of saving local copies (no support for alternate). However, the current implementation of Asset::getLocalThumbnailUri() contains a significant amount of code about handling asset versioning (becoming obsolete now).
