Fix debug memory crash on exit in VS22 due to recent TheGlobalData refactor

[helmutbuhler]

Since #1068 was merged, a false debug error appears during game cleanup in VS22 and in Debug mode:

It's because TheGlobalData is allocated much earlier now (probably earlier than the DebugMemoryTracker) and during deallocation it complains (probably because the memory debugger doesn't know about the allocation).

I think we can fix this by changing GlobalData.cpp:
GlobalData* GlobalData::m_theOriginal = NULL;
into
GlobalData GlobalData::m_theOriginal;
and use that as storage for the first GlobalData instance.

The reason this is screwing up we call new inside new, which will create the DynamicMemoryAllocator twice...
