AppConfigUnInit
BUG 89144: Uninit AppConfig but do it from the MTA
When AppConfig is inited, it is done on a WAM thread. WAM
threads are MTA threads. At that time we register an event
sink to get Metabase change notifications. Now, during shutdown,
we are running on an ASP worker thread, which is an STA thread.
That means we will get an RPC_E_WRONGTHREAD error shutting down. The
fix is to make the uninit call happen on an MTA thread.
This cover is used to do the work in the MTA.
