- 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)

UnrealHeaderTool: Update #include paths to be relative to the module's first public include path (or the generated UHT path if no public include paths are available) rather than the module's parent directory

* Added support for ".ubtignore" files that can be put in a folder to make ubt ignore the folder and its subfolder
* Fixed bug where project's plugin and source folder were visited multiple times (look in FileMetadataPreftch.cs)
* Changed so Lazy<File/DirectoryItem> is resolved directly on windows platform and only do the extra refresh on mac/linux (there seems to be some bugs on those platforms and we don't want to pay extra cost on windows)
* Added runtimeconfig.template.json and changed UnrealBuildTool to use server gc and a few more settings that improve performance
* Added so all file traversing paths is aware of .uplugin
* Added debug code to be able to write out which files that have been touched during UBT execution. This can serve as a way to identify places to add .ubtignore files

Added support for props file for UBT plugins. Needed for packaging of plugins having a ubt plugin

- so they can be independently wiped
- fix for build errors caused by stale files leftover from moved/renamed UBT module
