Description

## Enhancement
Currently, `PointGetPlan` and `BatchPointGetPlan` don't support `Clone()` method. This makes a execution plan unable to run `Apply` in parallel if there are PointGet/BatchPointGet in the inner side (see `enableParallelApply()`).

I'm not sure if there are some reasons that we can't simply enable parallel apply for PointGet/BatchPointGet, or we just didn't implement them.
