ANDROID: binder: Add BINDER_GET_NODE_DEBUG_INFO ioctl
The BINDER_GET_NODE_DEBUG_INFO ioctl will return debug info on
a node. Each successive call reusing the previous return value
will return the next node. The data will be used by
libmemunreachable to mark the pointers with kernel references
as reachable.
