btrfs: add a btrfs_csum_type_size helper
This is needed in btrfs-progs for the tools that convert the checksum
types for file systems and a few other things. We don't have it in the
kernel as we just want to get the size for the super blocks type.
However I don't want to have to manually add this every time we sync
ctree.c into btrfs-progs, so add the helper in the kernel with a note so
it doesn't get removed by a later cleanup.
