 Code Modernization: Remove JSON related polyfills.

 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]), JSON extension
 related polyfills and backwards compatibility code can now be removed.

 This change removes the `json_last_error_msg()` and `JsonSerializable`
 polyfills included in WordPress for full JSON extension support in PHP <
 5.6.

 Follow up of [46205-46206].

 See #47699.
 Props jrf, Clorith, pento.
