ARM64: Missing implementations for _Interlocked* "intrinsic" functions

Since VS 17.14.36203.30 / MSVC 19.44.35209.0 the default behavior on ARM64 is to not inline _Interlocked* functions, but to link them to implementations in msvcrt.lib (../vcstartup/.../arm64/atomics.obj) to handle architectural differences between Armv8.0 and Armv8.1+. We lack these function implementations.

Currently this is disabled by a compiler switch ("/forceInterlockedFunctions-")
