RFR: 8152896: Convert PrintCompressedOopsMode to Unified Logging

[Vladimir Kozlov]

Looks fine except next change. Do we have a test which parse this output?:

!   st->print("heap address: " PTR_FORMAT ", size: " SIZE_FORMAT " MB",
!   st->print("Heap address: " PTR_FORMAT ", size: " SIZE_FORMAT " MB",

Thanks,
Vladimir
