ipn/ipnstate, wgengine/wgint: add handshake attempts accessors

Browse Source 
Not yet used. This is being made available so magicsock/wgengine can
use it to ignore certain sends (UDP + DERP) later on at least mobile,
letting wireguard-go think it's doing its full attempt schedule, but
we can cut it short conditionally based on what we know from the
control plane.

Updates #7617
