Previously, the logic for enabling and disabling language features in flow analysis and type inference tests relied on setters in the `Harness` class that (a) were mostly unmatched with getters, and (b) were almost exclusively used in just a single one direction (e.g. `Harness.legacy` defaulted to `true`, so it was only ever set to `false`). Cleaned up so that there are explicit `enable` and `disable` methods in the `Harness` class to cover all the use cases.
