This adds flags and env variables for the following settings to runtime tests: - `per_test_timeout`: A per-test timeout which can be shorter than the batch timeout. Useful to cap the duration of tests which flake by getting stuck (as is the case for `bug60120.phpt`) - `runs_per_test`: Number of times to run each test (useful to detect flakes). - `flaky_is_error`: Controls whether a flaky test is considered passing or failing for batch error code purposes. Useful when either diagnosing a flaky test, or diagnosing a consistently-failing test while bypassing flaky others. - `flaky_short_circuit`: If a test is found to be flaky, declare it as such immediately, rather than waiting for the rest of the `--runs_per_test` to finish. Speeds up bisecting flaky test, at the cost of flakiness percentage accuracy. PiperOrigin-RevId: 466791296
