Subject: [PATCH] Initialize logging facility when running ProcessGroupNCCLTest
 (#112809)

If code is compiled without `glog`, there are no way to control log levels other than explicitly calling `c10::initLogging()`

Test plan: Run `TORCH_CPP_LOG_LEVEL=0 ./bin/ProcessGroupNCCLTest` and observe extra log messages
