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

[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
