Move CHANGELOG entry for rails#44179 to railties [ci-skip]

The CHANGELOG entry for rails#44179 originally focused on
`ActiveSupport::MessageVerifiers` and `ActiveSupport::MessageEncryptors`,
and made sense in `activesupport/CHANGELOG.md`.  However, prior to
merge, the focus changed to `Rails.application.message_verifiers`.
Therefore, the CHANGELOG entry should be in `railties/CHANGELOG.md`.
