RFR (S): 8204082: Make names of Young GCs more uniform in logs

[Thomas Schatzl]

Hi,

  during some more discussion about the messages there was the concern
that the "Concurrent End" message is not really an indication of the
concurrent marking end (this happens asynchronuosly), also that pause
may not occur (if no mixed gc starts after marking), so we came up with
"Prepare Mixed" for it.
"Concurrent End" would probably fit better for the current "Cleanup"
pause.

I.e.

Pause Young (Normal) ...
Pause Young (Concurrent Start) ...
Pause Young (Prepare Mixed) ...
Pause Young (Mixed) ...

Thanks,
