Add type annotations (parameter types and `-> None` return types) to all
top-level test functions across 22 test files. This enables mypy to

hidden.
_execute_multiple_query only disables batching on JSON_DECODE_FAIL_ERROR / INTERNAL_UNKNOWN_ERROR (#1025). This change applies the same pattern to a TimeoutError raised while sending a batch: set the batch size to 1 and raise _RetryableError.
