- Creates the UnrealArchitectures class, which wraps a list of UnrealArch objects
- UnrealArch is a single architecture, expandable enum-like struct
- There is no more concept of "no/default architecture", there is always a valid active architecture when building
- Most uses of "string Architecture" are replaced with one of the two above, depending if multiple architectures are supported or not
- UnrealArch has some platform-extensions for platform-specific naming (like Linux adds in LinuxName that turns, for instance, Arm64 -> aarch64-unknown-linux-gnueabi, which is used in folder names, etc)
- UnrealArch has bIsX64 which can be used determine intel instruction set (as opposed to arm)
- TargetRules class has an "Architecture" accessor that will return a single architecture if the active architectures is a single architecture, or throw an exception if multiple. This is useful in a majority of the cases where a paltform can only have a single architecture active in TargetRules (microsoft platforms, for instance, will create separate targets when compiling multiple architectures at once)
- Added UnrealArchitectureConfig class, which contains all the architecture information for a platform (what architectures are supported, what ones are currently active for given project, etc)

Requires implementing IComparable\IEquatable in FileItem (and I also implemented them in DirectoryItem for consistency)

* Added IWYU toolchain which can be enabled with -IWYU
* Added IWYU mode that can be used with -Mode=IWYU. This can be used to modify code files
* Binary of include-what-you-use that contains a ton of fixes to make ue build

- ConvertToReadableArchitecture() - turn an internal platform arch string to a printable version
- IsX86Architecture() - returns true if the platform arch string represents an x86 architecture
- Changed Linux to use the HumanReadableName as the FolderNameForArchitecture, so it's shorter and it is not obfuscated anymore

- Mac changes to compile separately, but link together (with lipo) after making two .dylibs/executables
- Removed FixDylibDependencies on Mac by making "stub dylibs" to mimic what Windows does with import libs, to solve circular dependencies
- Added DependenciesToSkipByArchitecture to ModuleRules that is used, when making a new single-arch LinkEnvironment from a multi-arch LinkEnvironment, to strip out libraries, etc, that should not be included with that single architecture
