A task that represents the asynchronous
'DeleteVariableHandle' operation. The ResultAds parameter
contains the ErrorCode after

It is a good practice to release all variable handles after use to regain internal resources in the TwinCAT subsystem. The composite method to this DeleteVariableHandleAsync(UInt32, CancellationToken) is the CreateVariableHandleAsync(String, CancellationToken)
