Coding Standards: Use static closures when not using $this.
When a closure does not use `$this`, it can be made `static` for improved performance. Static closures are supported in PHP since PHP 5.4. Props jrf, hellofromTonya, swissspidy, SergeyBiryukov. See #53359. git-svn-id: https://develop.svn.wordpress.org/trunk@51657 602fd350-edb4-49c9-b593-d223f7449a82
