[mediawiki/extensions/CentralAuth@master] Create the 'Global rename script' system user when needed

https://gerrit.wikimedia.org/r/951177

Api works: https://en.wikipedia.org/w/api.php?action=query&list=logevents&leuser=Global%20rename%20script

Indirectly broken by https://gerrit.wikimedia.org/r/c/mediawiki/core/+/934458 with the addition of 'exists' => true.
There are log entries also under non-existing user names: When rename get broken, user merges, very old entries, system users, after deletion via maintenance script.
As the logs are a history, there should be a listing even for non existing values, a error for invalid values is okay.
It would be okay to say the user does not exists, like done on Special:Contributions, but when there is a actor id the query should be done.

This patch will avoid the issue for any future uses of the fixStuckGlobalRename.php script, but we'll need to do something to fix the existing log entries. I think we just need to run User::newSystemUser( 'Global rename script' ) on every wiki, and that will create the user and magically assign the log entries to it. There doesn't seem to be a maintenance script that allows doing this, so I guess I'll need to write one (or maybe add an option to fixStuckGlobalRename.php).

I filed this as T344773 – it's worth fixing, but I think we should also fix the missing 'Global rename script' system user, which will resolve the problem as well.

@Krinkle suggested not merging the change into master, but only the current WMF branch, and running the script, since we'll only need to do it once. This is now done (https://wikitech.wikimedia.org/w/index.php?title=Server_Admin_Log&diff=2104245). I can view the list at https://en.wikipedia.org/wiki/Special:Log/Global_rename_script.
