Made a change in python API to support the GPU version of unique OP working in static graph (#27899)

* Made a change to support unique op working in static graph

* Correct python format error

* 1. remove paddle.unique_with_counts api, which counts as unique api
2. add paddle.math.increment(x, value=1.0, name=None) api
3. replace paddle.sums with paddle.add_n api
4. update paddle.metric.accuracy api (add name parameter)
