beforeInvalidate and afterInvalidate events

[ponderingexistence]

Describe the problem

I have a progress bar at the top of my site that appears upon every navigation that happens client-side (much like the one in kit.svelte.dev). I'm using the beforeNavigate and afterNavigate events to show and then hide the progress bar.

Occasionally I need to call invalidate() to re-run all the load functions (because the authentication status has changed, for example). I would like to show the same loader when the load functions are re-running as well — because when you think about it, running invalidate() is kind of life refreshing the page.

Describe the proposed solution

It would be nice if SvelteKIt provided two other lifecycle functions called beforeInvalidate and afterInvalidate or something along those lines.

Something like this would be good, although we would probably make it a store (similar to $navigating) rather than an event because you can't cancel it (you can cancel navigation in beforeNavigate).

[Rich-Harris]

In #6522 we trigger beforeNavigate and afterNavigate for invalidations (you can discriminate based on type), and also set the $navigating store, which makes these additions unnecessary

Ignore my previous comment, we ended up not merging that PR. See the discussion therein for details
