 #!CommitTicketReference repository="" revision="46455"
 Upgrade/Install: Detect the presence of the native PHP JSON extension
 before updating.

 The PHP native JSON extension has been bundled and compiled with PHP by
 default since version 5.2.0. Because the minimum version of PHP required
 by WordPress is now 5.6.20 (see #46594 and [45058]), the related polyfills
 and workarounds have been removed (see [46205-46206,46208]).

 However, even though the JSON extension is now included in PHP by default,
 it is still possible to disable the extension in a custom configuration.
 This change will prevent sites from upgrading if the JSON extension is
 disabled to prevent compatibility issues.

 Props jrf, jorbin, dd32, desrosj.
 Fixes #47699.
