Hard deprecate codepaths where tidy is disabled

Hard deprecate codepaths where tidy is disabled

Future parsers will not support the output generated with tidy disabled.

Parser tests using untidied output will also be deprecated (and
rewritten) in a follow-up patch.

No new release notes necessary since user-visible tidy configuration
was deprecated previously (in 1.32), and individual methods which had
disabled tidy during execution were individually release-noted as they
were updated.
