Subject: wmap_finalize: refactoring to rename variables

* gc.c (wmap_final_func): rename variables to clarify the meaning.
  In wmap2obj the key is WeakRef and the value is referenced object.
  In obj2wmap the key is referenced object and the value is an array
  of WeakRef.

* gc.c (wmap_finalize): ditto.
  [ruby-core:49044] [Bug #7304]
