Fabian Boehm f1e19884fb Add set --no-event ...

This allows running `set` without triggering any event handlers.

That is useful, for example, if you want to set a variable in an event
handler for that variable - we could do it, for example, in the
fish_user_path or fish_key_bindings handlers.

This is something the `block` builtin was supposed to be for, but it
never really worked because it only allows suppressing the event for
the duration, they would fire later. See #9030.

Because it is possible to abuse this, we only have a long-option so
that people see what is up.
