[feature] support npu allocator

Add distribution supported

usleep function in <unistd.h> only takes argument less than 1,000,000. Current call can exceed this limit, we have to fix it. This PR can fix random CI error.

* optimize memcpy perf for kunlun

* remove useless unitest for kunlun mean

* minor

* - Added UT for testing elementwise_mul caching

* lint fixes

* Polish and Optimize the print/repr message of all layer

* fix some code format

PADDLE_RETRY_CUDA_SUCCESS used wrong sleep time so it can cause timeout in unittest. This PR fixed it.

After we searched the doc in https://pubs.opengroup.org/onlinepubs/7908799/xsh/unistd.h.html, the time unit of sleep in unistd.h takes "seconds", usleep takes "microseconds", Sleep in windows.h takes "milliseconds".

* flush denormals to zero, test=develop

* add comments, test=develop

* Support MIPS arch.

* enable bilateral_slice unittest on windows platform

* reduce max threads

* add support for complex grad accumulated

* add unittest for coverage

* update test dtype

* remove useless blank line

Add Retry Logic to CublasHandlerHolder to avoid random unittest failure.

* - Reimplemented elementwise_add grad

- lint

* - fix after review

* - Fix to fix after review

* Windows generate pdb and dump, for debug

* fix code style, test=develop

* modify cmakelist

Modify CublasHandleHolder from using PADDLE_ENFORCE_CUDA_SUCCESS to PADDLE_RETRY_CUDA_SUCCESS to fix random unittest failure. We checked that the unittest log showed CUDA allocation error at this file, which may due to GPU not enough. We fixed similar failure in the past, so we applied PADDLE_RETRY_CUDA_SUCCESS here.
