Add support for building macOS disk images

This allows users to build drag 'n' drop installers with custom
backgrounds, volume icons, and icon layouts. Unlike other solutions,
disk images with these features can be built without any reliance on
AppleScript, Finder, or a graphical login session, making it (mostly)
reproducible and CI-friendly. .DS_Store files and their contained alias
and bookmark records (which control the mounted disk image's appearance
in the Finder) are written on-demand based on qbs properties defined in
the project file, as well as the Carbon LPic, TEXT, styl, and RTF
resources used for embedding a license agreement prompt.

Task-number: QBS-416
