 Boostrap/Load: Improve forward compatiblity of plugin global backup
 methods.

 [37588] added methods to backup the plugin globals, for ensuring that
 advanced cache drop-ins don't overwrite hooks that've been added earlier
 in the load process.

 The method for restoring the plugin globals wasn't compatible with the
 implementation of `WP_Hook` in #17817. `WP_Hook` implements `ArrayAccess`,
 so `_restore_plugin_globals()` was treating it as an array, and
 inadvertantly overwriting the `WP_Hook` object with a plain array.

 To avoid having to re-write this code as part of #17817, we now use
 `add_filter()` to restore any hooks that were added by cache drop-ins,
 which `WP_Hook` correctly supports.

 Props pento, jorbin.
 See #36819.
