RFR: 8367422: Parallel: Refactor local varibles names in copy_unmarked_to_survivor_space

Thu Sep 11 14:07:54 UTC 2025

Trivial "renaming" a local variable and its type to better reflect its semantic and avoid much `HeapWord*`-vs-`oop` conversion.

Test: Comparing the generated asm in release build and they are identical.
