Comment (by spacedmonkey):

 In [changeset:"55818" 55818]:
 {{{
 #!CommitTicketReference repository="" revision="55818"
 Networks and Sites: Load `WP_Metadata_Lazyloader` class file if class does
 not exist.

 Follow on from [55747].

 As `get_sites` can be called very early in the bootstrap process, like in
 the sunrise.php file, it means that the `WP_Metadata_Lazyloader` may not
 have been loaded yet in the wp-settings.php file. Add a simple check to
 see if the class exists and if it does not exist then load the class file
 in.

 Props spacedmonkey, peterwilsoncc, dd32.
 See #58185.
