Add an explicit return type for useReadQuery

[jerelmiller]

The useReadQuery hook currently uses type inference for the return type from the hook. For consistency, I added a UseReadQueryResult type that can be used to get a typed return type rather than having to rely on typeof useReadQuery, which doesn't allow the use of the generic TData type argument.

I marked this as a patch since this is a fully backwards compatible change. I'm happy to move this to a minor and merge this into release-3.9 if that makes more sense.
