DeviceGetStreamPriorityRange(out Int32, out Int32)
Returns numerical values that correspond to the least and greatest stream priorities.
Returns in *leastPriority and *greatestPriority the numerical values that correspond to the least and

greater priorities. The range of meaningful stream priorities is given by [*greatestPriority, *leastPriority].
If the user attempts to create a stream with a priority value that is outside the the meaningful range as
specified by this API, the priority is automatically clamped down or up to either *leastPriority or
*greatestPriority respectively. See cudaStreamCreateWithPriority for details on creating a priority stream.
A NULL may be passed in for *leastPriority or *greatestPriority if the value is not desired.
This function will return '0' in both *leastPriority and *greatestPriority if the current context's device
does not support stream priorities (see cudaDeviceGetAttribute).
