Describe the Bug

When attempting to use InferGetStaticPropsType I am getting my parameters' type as never.

The following link describes my issue.

#11842 (comment)

To better explain the bug - the bug only occurs if I include the following in getStaticProps:

  if (!res) {
    return {
      notFound: true
    }
  }

  if (res.length === 1) {
    return {
      redirect : {
        destination: `/city/sydney`,
        permanent: false
      }
    }
  }

It seems that including:

    return {
      notFound: true
    }

and:

    return {
      redirect : {
        destination: `/city/sydney`,
        permanent: false
      }
    }

will not allow for InferGetStaticPropsType to infer the correct type.

It also seems that including the type GetStaticPaths and GetStaticProps will force the InferGetStaticPropsType to return any as the type as seen in the thread below.
#11842 (comment)

I believe the most important bug to fix in this case is that the infer for getStaticProps only works in the case where we only return props. Not in the face where we may return redirect or notFound.

Expected Behavior

My static props type should be inferred however they currently are not.

To Reproduce

Set strict mode enabled and attempt to use InferGetStaticPropsType.

Hi, this is a duplicate of #15913 so closing this in favor of that one.
