enhancement: Export additional types from @remix-run/react

[chaance]

This PR exposes additional types that are helpful when passing values via context or props.

Complex return types from functions should be exposed directly IMO. Usage is a little simpler than relying on ReturnType<typeof someFunc>, and in the case of generics like Fetcher and FetcherWithComponents it is necessary.

// instead of this...
type Ctx = {
  fetcher: ReturnType<typeof useFetcher>;
  location: ReturnType<typeof useLocation>;
};

// ...I can do this
type Ctx = {
  fetcher: FetcherWithComponents<SomeData>;
  location: Location;
};

Another good type to export would be Transition, instead of ReturnType<typeof useTransition>.
I used to be able to import it from import type { Transition } from "@remix-run/react/transition"; but this is no longer possible, and there's no export for @remix-run/react.

I'm not sure if you can update this PR with this very similar request or if I should make a new one, let me know 😄
