- 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)

Added UE Start/End comments around every UE modification for easier merge sanity checking in the future.

If you still need to old behavior of searching for a library we use the new PublicSystemLibraries instead (used very sparingly).
Also updated conventions on importing Android libraries to use the newly introduced Android Architecture instead, which is always set to a valid architecuture (unlike Target.Architecture for the general case)
Lastly I updated some build.cs files that were doing filesystem enumeration or copying as they were being parsed, this is highly discouraged (partially because we cache filesystem operations but also it adds a cost to something we expect to be very fast). Any operations like this should be done as part of the build if they have to be done at all.
