8307346: Add missing gc+phases logging for ObjectCount(AfterGC) JFR event collection code

[olivergillespie]

Backport for 8307346

This would be clean, except 8280450 adds some inconsequential code immediately after the hunks in g1 and parallel for reporting task queue stats, which causes a trivial conflict.

Please enable pre-submit checks on this repo, and backport to 20u.

[olivergillespie]

They're enabled now, but not sure how to re-trigger. Must 20 be done before 17?

[phohensee]

You can request both 17 and 20 at the same time, so just post a 20u PR. I don't actually know how to provoke a pre-submit run, but I'd try a merging your branch with master.

[olivergillespie]

Triggered the checks, and they're passing. The bug is approved for 17u backport. I created openjdk/jdk20u#79 for 20.

[phohensee]

Please add a /integrate comment and I'll sponsor.
