Add pretty-printing for PasswordStore::FormDigest

Add pretty-printing for PasswordStore::FormDigest

This helps when printing FormDigest objects to logs during debugging.

autofill::PasswordForm has a similar operator but implemented through JSON
stringification for better flexibility. FormDigest does not need this, because
it only has 3 members and is unlikely to grow.
