8331385: G1: Prefix HeapRegion helper classes with G1

[tschatzl]

trafficstars

Hi all,

after JDK-8330694 which renamed HeapRegion to G1HeapRegion, there were a few related helper classes in this CR that were not renamed.

It's purely mechanical renaming without even further renaming of files etc.

This change updates them.

(Fwiw, the "Viewed" checkbox at the top right of the file change helps a lot review this change incrementally)

Testing: tier1, tier4, tier5

Thanks, Thomas
