btrfs-progs: Introduce btrfs_raid_array and related infrastructures
As part of the effort to unify code and behavior between btrfs-progs and
kernel, copy the btrfs_raid_array from kernel to btrfs-progs.
So later we can use the btrfs_raid_array[] to get needed raid info other
than manually do if-else branches.
