External Libraries: Update the phpass library to version `0.5`.

This updates the phpass library from version `0.3` to the latest version of `0.5`. This is a minor update that includes some adjustments to be more friendly with newer versions of PHP.

The changes made in [30466] have also been applied to the new version of the library. This should now be the only WordPress specific modification do this library.

Props ayeshrajans, dd32, otto42, desrosj.
Fixes #51549.
