Detailed Description

Access to internal garbage collector rachability flags. Only GC and GC related functions can use these. NOTHING except GC should be manipulating reachability flags (including EInternalObjectFlags::Unreachable). EInternalObjectFlags::Unreachable is the ONLY reachability flag that can be safely READ by non-GC functions. Reading ReachableObjectFlag and MaybeUnreachableObjectFlag outside of GC is NOT THREAD SAFE.
