Obtain the control-rate for this this.
Audio processing Element objects will use this rate to sub-divide their processing
loop and call sync_values in between. The length of the processing segment should
be up to control-rate nanoseconds.
If the this is not under property control, this will return CLOCK_TIME_NONE. This allows the element to avoid the sub-dividing.
The control-rate is not expected to change if the element is in PAUSED or PLAYING.
