Describe the bug

When using the require-selections rule with the requireAllFields option, a selection on a type that has any of the fieldNames is demanded to include all of the fieldNames, whether or not they exist on that type.

To Reproduce Steps to reproduce the behavior:

I've included a unit test in my PR #2912 that reproduces the error: dfdda86

The issue occurs when requireAllFields is set true and a given type implements only some of the specified fieldNames. e.g. given a schema

  type User {
    id: ID
    name: String
    posts: [Post]
  }

  type Post {
    id: ID
    title: String
    content: String
    author: [User!]!
  }

a rule config

{ requireAllFields: true, fieldName: ['id', 'title', 'content'] }

and a document

        {
          user {
            id
            posts {
              id
              title
              content
            }
          }
        }

the rule will report that you must select the user.title and user.content fields, even though they don't exist.

Expected behavior

The lint rule should not fail selection sets based on the absence of fields that cannot be selected in that context.
