bcachefs: track_event_change()
This introduces a new helper for connecting time_stats to state changes,
i.e. when taking journal reservations is blocked for some reason.
We use this to track separately the different reasons the journal might
be blocked - i.e. space in the journal full, or the journal pin fifo
full.
Also do some cleanup and improvements on the time stats code.
