RFR: 8351369: [macos] Use --install-dir option with DMG packaging

Wed May 28 07:16:30 UTC 2025

- `--install-dir` option in DMG packaging is no longer ignored.
- Defaults are still the same: `/Applications` and `/Library/Java/JavaVirtualMachines`.
- If the installation directory doesn't exist, jpackage will try to create and delete it right after the DMG package is created.
- If jpackage was unable to create installation directory error will be thrown or if installation directory points to invalid location like file.
- It will be user responsibility to make sure installation directory exist on target machine, since DMG cannot create directories during drag and drop.
- Target directory in case of non-default installation dir will display full path. See image below for example.
