feat: parameter for running outro transitions on $destroy

[ehrencrona]

Make it possible to run outro transitions when manually calling $destroy on a component.

In Svelte 4, the workaround mentioned in #4056 no longer works because those APIs are not public / exported.

Fixes #4056

If we want to do this, we should strongly consider having it be an options object (with only one option for now), rather than being a positional parameter that we may come to regret.
