fix(vue-query): parameterize suspense return type by TResult

The previous shape pinned `suspense` to `Promise<QueryObserverResult<TData,
TError>>` inside the distributive conditional, so awaiting `suspense()` lost
type precision when `UseBaseQueryReturnType` was instantiated with
`DefinedQueryObserverResult` (data became `TData | undefined` again) or
`InfiniteQueryObserverResult` (no `fetchNextPage`/`hasNextPage`/`data.pages`).

Lifting `suspense` outside the distributive arm and typing it as
`Promise<TResult>` keeps the per-property mapping distributive but lets the
suspense result carry the parameterized observer type — matching the runtime
already returned by `observer.fetchOptimistic()` / `getOptimisticResult()`.
