Fixed some API that were mistakenly setup as generic struct API instead of class API.
Removed some unused API.
No functional changes, just code reorg.

[CL 16727641 by Tim Smith in ue5-main branch]
Added new casting system betwen the different type definitions. This allows some patterns that makes the code easier.
Moved some direct calls to engine API to FClasses.
More property data moved to the property definition.
Replacing a many more instances of referencing engine type directly with referencing UHT types.
Removed the FToken from the property data. Saved 600MB of memory on some titles.

2) Remove the global hash storage system since it is moved into the Function type information.
3) Remove some unsed classes and methods.
4) Added the TEMPORARY auto creation of base engine types until they can be added to the no export file.

1) Refactored preparsing to scan for @UCLASS, @USTRUCT, and @ENUM and define then. This means that no new entries into the type definition info system will be added after pre-parsing and thus remove the need for any type of locking during code generation.
2) Parsing and code generation is now being done in a strict order based on dependencies and no longer by project. This removes the need of explicitly parsing depedencies first or waiting on hashes to be computed. (Provided a 50%-80% improvement in code generation time)
3) Changed HeaderParser to be specific to one source file. Removed the need to pass the source file around since it is always known at construction time. Simplified some error handling logic.
4) Changed parallel for loops to using event graph to provide more concurrency.
5) Refactored the main program flow into concise steps.
Testing:
Verified that the headers generated exactly the same for:
1) First person C++ Project
2) UnrealEditor
3) QAGame
4) ShooterGame
5) FortniteGame
FYI: Marc had reviewed this as part of a larger change but some parts were extract. These are the remaining changes.

MAJOR FEATURES + CHANGES
==========================
Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.
