[Feature]: useLocation supports generics

[guaijie]

What is the new or updated feature that you are suggesting?

type State = { from : string; base: string}
const location = useLocation()

// types
export declare function useLocation<T = unknown>(): Location;
export interface Location extends Path {
state: T;
key: Key;
}

Why should this feature be included?

Better type inference experience

This would actually remove type safety, as you would be overriding state to that type. You should be using type narrowing to determine the type of state safely. A generic would be a hack to force that to work.
