This is the first step in refactoring Worklist to allow arbitrary
number of local worklists with private segments:
- Introduce MarkingWorklistImpl<> which will eventually replace
(and will be renamed to) Worklist.
- MarkingWorklistImpl<> owns the global pool of segments but does not
keep track of private segments.
- MarkingWorklistImpl<>::Local owns private segments and can be
constructed dynamically on background threads.
- Rename the existing MarkingWorklistsHolder to MarkingWorklists.
- Rename the existing MarkingWorklists to MarkingWorklists::Local.
- Rename the existing marking_workists_holder to marking_worklists.
- Rename the existing marking_worklists to local_marking_worklists.

native contexts for the new memory measurement API.
