josh adams 1610c3bee3 UnrealArch/UnrealArchitectures changes ...

- 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)
