[PATCH v3 1/2] btrfs: move definition of btrfs_raid_types to volumes.h

[Qu Wenruo <wqu@suse.com>]

It's only internally used as another way to represent btrfs profiles,
it's not exposed through any on-disk format, in fact this
btrfs_raid_types is diverted from the on-disk format values.

Furthermore, since it's internal structure, its definition can change in
the future.
