tests: Add a generalized write-roundtrip test
This test tests two important invariants: - Every combination of write flags has to result in a valid document - Parsing that document and saving the result has to result in identical output We don't test all flags since parse_no_escapes can intentionally result in malformed documents and other flags aren't relevant for node output. Also note that we test both no-whitespace and whitespace version to make sure we don't have unnecessary whitespace added during formatting.
