Upgrade/Install: Create a temporary backup of plugins and themes before updating. 

This aims to make the update process more reliable and ensures that if a plugin or theme update fails, the previous version can be safely restored.

* When updating a plugin or theme, the old version is moved to a temporary backup directory:
 * `wp-content/upgrade/temp-backup/plugins/[plugin-slug]` for plugins
 * `wp-content/upgrade/temp-backup/themes/[theme-slug]` for themes.

* If the update fails, then the temporary backup kept in the `upgrade/temp-backup` directory is restored to its original location.
* If the update succeeds, the temporary backup is deleted.

To further help troubleshoot plugin and theme updates, two new checks were added to the Site Health screen:
* A check to make sure that the `temp-backup` directory is writable.
* A check that there is enough disk space available to safely perform updates.

To avoid confusion: The `temp-backup` directory will NOT be used to "roll back" a plugin to a previous version after a completed update. This directory will simply contain a transient backup of the previous version of a plugin or theme being updated, and as soon as the update process finishes, the directory will be empty.
