fix pool2d pool3d,support asymmetric padding and channel_last (#19739) 

* fix pool2d pool3d:
1. support asymmetric padding;
2. support padding algorithm:"SAME" and "VALID";
3. support channel_last: data_format NHWC and NDHWC;
4. support inferring shape when input with negative dims in compile time;
5. change doc of python API and c++;
6. fix bug in cuda kernel when Attr(adaptive) is true.

test=develop,test=document_preview

* fix 'tensors' to 'Tensors'. test=develop,test=document_preview

* add test for converage ValueError.test=develop,test=document_preview

* resolve conflict in test_pool2d. test=develop

* \brief Getting pooling results, and calculating gradient.

* In pool2d, all tensors are in NCHW format. Where N is batch size, C is the
* number of channels, H and W is the height and width of feature.
* In pool3d, all tensors are in NCDHW format. Where N is batch size, C is the
* number of channels, D, H and W is the depth, height and width of feature.
* In pool2d, all Tensors are in NCHW or NHWC format. Where N is batch size, C
* is the number of channels, H and W is the height and width of feature.
* In pool3d, all Tensors are in NCDHW or NDHWC format. Where N is batch size, C
* is the number of channels, D, H and W is the depth, height and width of
* feature.
*
* In max pooling, it is possible that the pooling region has multiple maximum
* elements. In this case, we should compute the gradient of the first maximum
