From 7e2009642abc2bddf3091d091b0d8d9ead871b2b Mon Sep 17 00:00:00 2001

Subject: [PATCH] Load: Re-add `locale.php`.

`locale.php` is occasionally included directly by custom external code, so should continue to be available. This behaviour is deprecated.

Partial revert of [38364].
See #37827, #39027.
