Expose the clock and frequency in CtfTmfTrace

The frequency of the CtfTmfTrace is currently exposed in an indirect way using cyclesToNanos(). But sometimes there is the need to get direct frequency. This commit added public methods to get the direct frequency. [Added] public method to get clock info in CTFTmfTrace [Added] public method to get frequency in CTFClock Signed-off-by: Siwei Zhang <[email protected]>
