Conformance tests: Align automated and manual scoring

Start with conformance/src/unexpected_fails.py and inspect the remaining unchecked discrepancies for mypy/namedtuples_define_functional.toml, pyre/directives_reveal_type.toml, and pyre/namedtuples_define_functional.toml. Compare each automated result with its manual judgment and reconcile the remaining cases. Done means the three listed discrepancies are resolved and the conformance scoring agrees with the manual results.

In #1678 I added an automated tool for scoring the conformance test suite, and #1682 and #1683 added some features to support edge cases.

Now I am working on going through the remaining files where the automated conformance judgment on a file differs from the manual one (open PRs: #1684, #1685, #1687, #1688, #1689, #1690, #1691).

I'll use this issue to track the remaining discrepancies (from conformance/src/unexpected_fails.py):

• mypy/dataclasses_usage.toml: Pass vs. Fail (#1684)
