Move postGC out of CrossThreadPersistentRegion::LockScope

Move postGC out of CrossThreadPersistentRegion::LockScope

Some finalizers/prefinalizers acquire locks, causing a dead lock when CrossThreadPersistent tries to acquire the CrossThreadPersistentRegion lock.

This CL moves the postGC step outside of the CrossThreadPersistentRegion::LockScope. This should be okay as the CrossThreadPersistentRegion::LockScope only exists to avoid add/deletetion of CrossThreadPersistentNodes during marking.
