RFR: 8252921: NMT overwrite memory type for region assert when building dynamic archive [v5]

[Zhengyu Gu]

> Thread stack is currently unregistered with NMT in Thread's destructor. Apparently, only Java thread invokes destructor
> before thread exits.  For NonJavaThread, e.g. ConcurrentGCThread, thread may exit while its "Thread" object continues
> alive, therefore, its thread stack is still "alive" from NMT perspective. Once thread exits, the virtual memory for the
> thread stack can be reserved again, that confused NMT.  The solution is to move thread stack unregistration code to
> post_run() method.
