andrew rodham 7e74749c93 Core: Added a container for global debugging pointers that is visible to natvis ...

This new concept aims to abstract the complexities of dealing global debugging state that is tricky with the symbol resolution scoping rules in Visual Studio's natvis specification, and fragile with live-coding.
The specification causes natvis authors to often need to add explicit scoping to global variables (using {,,UnrealEditor-ModuleName.dll} or UnrealEditor-ModuleName.dll! scoping), which is fragile for different build types (Editor vs Server vs Client) and configurations (Debug, Shipping etc).

This change adds a GDebuggingState symbol to every dll with which any engine module or third-party library can register global pointers using a unique GUID. The GUID string can then be used to locate that pointer from any other module through a natvis intrinsic function using strstr, without having to inject a specific symbol name into every DLL.

This allows authors to write generic natvis expressions that will work robustly when being viewed from the context of any other module, or in code that has been patched by LiveCoding.
