macOS: Support Xcode Archiving for distributing application bundles

This is a port of iOS commit f3f8647 to main, for Xcode archiving to
also work for macOS bundles, allowing the bundle to be archived and
later distributed via Testflight, App Store Connect, etc...

Additonal Xcode property also had to be added to the extern draco shared
library target to prevent it from being included in the Xcode archive
(an implicit behavior for `SHARED` CMake libraries), without this,
the archive would get polluted, preventing it from being properly
recognized as a proper app bundle archive.
