[XFS] move xfs_bmbt_newroot to common code

Browse Source 
xfs_bmbt_newroot is a mostly generic implementation of moving from an
inode root to a real block based root. So move it to xfs_btree.c where it
can use all the nice infrastructure there and make it pointer size
agnostic

The new name for it is xfs_btree_new_iroot, following the old naming but
making it clear we're dealing with the root in inode case here, and to
avoid confusion with xfs_btree_new_root which is used for the not inode
rooted case.
