Add additional OS installer images

- Debian 11, Ubuntu 20.04, and OpenBSD 7.0 images
  - Menu is too long, so added pxeboot_boot_images list to determine
    which images to download/include in menu
- Update versions and checksums downloaded for existing images, and use
  version specific paths where applicable.
- Update boot parameters to better support EFI booting
- Update galaxy metadata
