RFR: 8331398: G1: HRPrinter reclamation events should print the original region type [v2]

[Thomas Schatzl]

> Hi all,
> 
>    currently, the various reclamation events always print `FREE` as the region type in the event string because the methods are always called after freeing.
> 
> This is kind of useless information (obviously reclaimed regions are `FREE` after reclaiming), so this CR suggests to use the original type to understand what region has been reclaimed.
> 
> It helped at least me a bit when debugging crashes after some refinement changes.
> 
> This is based on PR#19013, so please have a look at it as well.
> 
> Testing: local compilation, local testing
> 
> Thanks,
>   Thomas
