    [REACTOS] Finally get some ARM64 applications building (#4517)
    
    - Add some missing ARM64 exports to ntdll, kernel32 and user32
    - Create mmtypes header file based on WoA debug symbols
    - Get the remaining headers in order, so we can build ARM64 apps
    - Adjust subsystem version for binaries so they can run on WoA host
    - Get calc, notepad and more base apps to build for ARM64 platform
