- This allows for Confidential platforms to exist outside of the engine, and insert themselves in as needed
- Directory structure is, where .... mirrors the directory structure for Engine and projects
- /Platforms/XXX/....
- Moving to more data driven approach for ShaderPlatforms and PlatformInfo, where they can be read from DataDrivenPlatformInfo.ini files that live in the platform config folders
- Removed platform mentions from UBT, by way of changing some enums to partial classes with static members (see UnrealTargetPlatform)
- Various other UBT/UAT modifications to allow for looking in other locations for files
- THIS IS NOT A COMPLETE AND FINAL SOLUTION. WE WILL CONTINUE WORK IN DEV-BUILD BEFORE ITS READY FOR PRIMETIME
