disk: part_dos: Refactor to allow retrieving raw MBR partition data
Refactor the part_get_info_extended() helper function (which already
recursively traverses DOS partitions) to optionally return the raw MBR
partition structure (dos_partition_t).
This allows other subsystems, such as EFI, to retrieve the partition
details in the legacy MBR format.
