RFR: 8290177: Improve documentation in G1MMUTracker

Tue Jul 12 14:56:15 UTC 2022

Hi all,

  please review this change to improve the naming and documentation in `G1MMUTracker::when_sec`. Recently we have been looking at some young gen sizing issues (for another time), and it took some time to understand what the code does and how it works. This is kind of the result of this internal discussion, but I'm open to improve this further.

Testing: gha

Thanks,
  Thomas
