Toggle error or loading state in devtools

[paul-sachs]

I was recently debugging our error and loading states within our application and it struck me that this would be a killer feature to expose from the devtools. Currently we don't use react-query for anything crazy so devtools seem nice but not necessary since the network panel provides most of what i need, but toggling loading and error state is something that can't be done easily any other way.

Just wanted to gauge how interested other folks would be before I dive into the code and see if this is even possible.

Decided to go ahead and start a draft to see if it's possible. It's a little finicky to get errors handled with the onError. Might need to investigate an alternative to setting state on the cache entry...
