Expose TreeNode::children() publicly and use it to remove empty().

Since the public getter is const, this converts BookmarkModel (which was using a
non-const getter) to use direct member access, with a friend declaration.  Filed
bug 965314 about cleaning this up.

This also converts/comments the rest of tree_node_model.h in preparation for
removing child_count() and GetChild().
