bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)
Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.
