cmd,ipn/ipnlocal,tailcfg: implement TKA disablement

* Plumb disablement values through some of the internals of TKA enablement.
 * Transmit the node's TKA hash at the end of sync so the control plane understands each node's head.
 * Implement /machine/tka/disable RPC to actuate disablement on the control plane.

There is a partner PR for the control server I'll send shortly.
