profiler: add followerClock block

Browse source 
Add a new followerClock block in the profiler info. This is only set
when the follower could be a driver and it contains the clock info used
for following the driver, mostly the rate difference and delay.

Dump this info in pw-profiler -J

Make sure we always set the info in the clock, especially also when we
are following.
