Calculate frame timestamps based on target frame rate

Before this change HardwareVideoEncoder used capture time as frame
timestamp passed to HW encoder. That led to buffer overshoots with
HW encoders which infer frame rate from timestamps when frames were
dropped before encoding (i.e., frame rate decreases according to frame
timestamps) or when FramerateBitrateAdjuster was used.

Fixed this by using synthetic monotonically increasing timestamps
calculated based on target frame rate provided by bitrate adjuster.
