Programmatically load detailed version information about Xcode version via pyobjc on macOS

xcode_vers.py

# Warning - because of how this works, it loads classes into memory namespace.
# Attempting to load a second Xcode to inspect within the same python run will result in errors
# If you need to inspect multiple, for now, just spin the inspection up under a second process
