8256740: ZGC: Move closures out of zOopClosure files

[stefank]

zOopClosures.hpp and zOopClosures.inline.hpp contain a collection of different closures. There used to be a need to split closures and have them registered with the oop iterate framework, but that has been fixed with the last oop iterate framework rewrite.

I propose that we move the closures out to the sub-systems where they are used.
