Add context generic for LoaderFunction/ActionFunction

[ryanflorence]

Instead of this disaster:

type KCDLoader = (
  args: Omit<Parameters<Loader>['0'], 'context'> & {context: LoaderContext},
) => ReturnType<Loader>

type KCDAction = (
  args: Omit<Parameters<Action>['0'], 'context'> & {context: LoaderContext},
) => ReturnType<Action>

People can do this:

export let loader: LoaderFunction<KCDLoaderContext> = ({ context }) => {

}

Might it be worthwhile to also make MetaFunction and LinksFunction generic with respect to the args.data property?
