feat: add AND/OR logical criteria list in schema and query

[igdianov]

This PR adds schema and query support for AND/OR list criteria expressions, i.e.

query {
  Authors(where: { 
    OR: [
      { name: { LIKE: "Anton" } } 
      { name: { LIKE: "Leo" } }
    ]
  }) {
    select {
      id
      name
    }
  } 
}

will return

{
  "data": {
    "Authors": {
      "select": [
        {
          "id": 1,
          "name": "Leo Tolstoy"
        },
        {
          "id": 4,
          "name": "Anton Chekhov"
        }
      ]
    }
  }
}

Also, using nested relations criterias:

  Books(where: { 
    author: {
      OR: [
        { name: { LIKE: "Anton" } } 
        { name: { LIKE: "Leo" } }
      ]
    }
  }) {
    select {
      id
      title
    }
  } 

will return:

{
  "data": {
    "Books": {
      "select": [
        {
          "id": 2,
          "title": "War and Peace"
        },
        {
          "id": 3,
          "title": "Anna Karenina"
        },
        {
          "id": 5,
          "title": "The Cherry Orchard"
        },
        {
          "id": 6,
          "title": "The Seagull"
        },
        {
          "id": 7,
          "title": "Three Sisters"
        }
      ]
    }
  }
}
