The personal data export and erasure tools allow plugins to register their own callbacks, in order to add additional data to the export and erasure processes. Previously, these were registered without specifying a constant identifier in the array of callbacks. Using mutable integers makes it difficult for plugins to modify the callbacks of other plugins, though. Using associative array keys instead provides a covenient and reliable way to identify and interact with another plugin's callbacks. Props desrosj, allendav, ocean90. Fixes #43931.
