@cypher directives in where clauses

[Tanner-Scadden]

Is your feature request related to a problem? Please describe.
Would be awesome to be able to filter results by values that have a @cypher directive! Would help with filtering by values such as ages calculated on date of birth values.

Describe the solution you'd like
To include the @cypher directive values in the autogenerated where clauses. I don't imagine this would be too hard since the library adds these values to the sort by options.

Describe alternatives you've considered
N/A

Additional context
Example:

type User {
  id: String! @id 
  birthday: Date!
  age: Int!  @cypher(
        statement: """
        MATCH (this)
        return duration.inMonths(date(this.birthday), date()).years
        """
      )
}

query Users {
  users(where: { age_GT: 60 }) {
    id
  }
}

Hi, @Tanner-Scadden thanks for the request!
We are doing some investigation around this particular request that you can find here #2029.
I've added the duplicate flag as this request seems to me very similar to the #554.
