PHP7.3 compatibility: Fix compact throwing notices.

In PHP 7.3, the `compact()` function has been changed to issue an `E_NOTICE` level error if a passed string refers to an unset variable. In previous versions of PHP, this notice was silently skipped. The full RFC can be viewed here: https://wiki.php.net/rfc/compact.

Props jorbin, desrosj.

Merges [43819] and [43832] to trunk.

Fixes #44416.
