Fix inplace_abn compile error on Windows

SyncBatchNorm not compiled on Windows currently, which is used by inplace_abn OP, fix as follow:

• compile sync_batch_norm on Windows, for the NCCL functions is limited by #ifndef WIN32, compiling is ok
• If on WIN32, do not use sync_batch_norm in sync_batch_norm_pass.cc

Tested on windows OK
