a58e2e9623 Make sure the semaphore not be released during the lifecycle of SmChannel (#131)
Fix #126

 - Put `std::shared_ptr<SmDevice2DeviceSemaphore>` into the `SmChannel` 
 - add a `DeviceHandle` struct in `SmChannel`
 - add `DeviceHandle` template
 
Users need to write code like this to use channel in device side:
```
using DeviceHandle = mscclpp::DeviceHandle<T>;
__device__ DeviceHandle<mscclpp::SimpleProxyChannel> channel;
__device__ DeviceHandle<mscclpp::SmChannel> smChannel;
```

To cover a channel to deviceHandle, need to call this function:
`mscclpp::deviceHandle(SimpleProxyChannel or SmChannel)`
