From: Andrey Albershteyn <aalbersh@redhat.com>

The Merkle tree blocks and descriptor are stored in the extended
attributes of the inode. Add new attribute type for fs-verity
metadata. Add XFS_ATTR_INTERNAL_MASK to skip parent pointer and
fs-verity attributes as those are only for internal use. While we're
at it add a few comments in relevant places that internally visible
attributes are not suppose to be handled via interface defined in
xfs_xattr.c.
