scsi-disk: add MODE_PAGE_APPLE_VENDOR quirk for Macintosh
One of the mechanisms MacOS uses to identify CDROM drives compatible with MacOS
is to send a custom MODE SELECT command for page 0x30 to the drive. The
response to this is a hard-coded manufacturer string which must match in order
for the CDROM to be usable within MacOS.
Add an implementation of the MODE SELECT page 0x30 response guarded by a newly
defined SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk bit so that CDROM drives
attached to non-Apple machines function exactly as before.
