8277383: VM.metaspace optionally show chunk freelist details

[tstuefe]

I'd like to backport this to jdk17 since it adds a useful option for metaspace analysis. Fix is low risk and applies cleanly.

The commit being backported was authored by Thomas Stuefe on 7 Dec 2021 and was reviewed by Coleen Phillimore and Aleksey Shipilev.
