Waiting for supports of the mkldnn’s layout.

Please have a look at this pool operator supported by the MKLDNN’s layout and assess if we can keep this design of the code.

This code uses the implementation of layout which is available in the last pull-request. Therefore some of the function in this code are not available in this pull-request, but are available here

This version of code can be merged into the main branch when the pull-request with layout is accepted.

The concept of splits of the long code was proposed by @luotao1

Pull-request is related to #11040
