Message:

Upgrade/Install: Add a conditional to facilitate testing of the Rollbacks feature project.

The ​Rollback Update Failure feature project creates a temporary backup of plugins and themes before updating. This aims to make the update process more reliable and ensure that if a plugin or theme update fails, the previous version can be safely restored.

If the ​Rollback Update Failure plugin is installed, WP_Upgrader::install_package() will use the move_dir() function from there for better performance. Instead of copying a directory from one location to another, it uses the rename() PHP function to speed up the process, which is instrumental in creating a temporary backup without a delay. If the renaming failed, it falls back to copy_dir() WP function.

This conditional aims to facilitate broader testing of the feature. It is temporary, until the plugin is merged into core.

Props afragen, pbiron, costdev, davidbaumwald, audrasjb, jrf, SergeyBiryukov.
Fixes #56057. See #51857, #54166.
