Rename "disable_history" stack state to "noninteractive"

The commit after next will fix a bug where we wrongly disable prompt
history in some scenarios. The root cause is that life span of
"disable_history" does not model when we actually want to disable
history.

Let's rename the state variable to "noninteractive". It's set whenever
we are executing a hook, mapping or command.

Note that it's also active inside ":prompt"'s callback, which doesn't
play well with the new name :(
