File: Add helper function to locate shared containers on macOS and iOS

Browse source 
File::getContainerForSecurityApplicationGroupIdentifier will return the
path to a container which is shared between all apps using the specified
app group ID. This might be useful if you need to share resources
between a standalone app and an AUv3 plugin, for example.
