Request: support splitting and align long type annotations.

Would be great if yapf could format the code like:

```python
class Engine(
Generic[
_T_INIT_CONFIG,
_T_INIT_RESOURCE,
_T_RUN_CONFIG,
_T_RUN_OUTPUT,
]
):
...

class EngineExecutorAggregatorSelector(
Generic[
_T_RUN_CONFIG,
_T_RUN_OUTPUT,
]
): # yapf: disable

def __init__(
self,
pairs: Sequence[
Tuple[
EngineExecutor[
Any,
Any,
_T_RUN_CONFIG,
_T_RUN_OUTPUT,
],
float,
]
],
):
...
```
