[FEAT]Mapper supports interface extends

[kgtkr]

Is your feature request related to a problem? Please describe. Currently mapper does not recognize extended fields in interface

# schema.graphql
type Test {
  id: ID!
  name: String!
  description: String!
}

// schema.mappers.ts
interface Base {
  description: string;
}

export interface TestMapper extends Base {
  id: string;
  name: string;
}

// Test.ts
import type   { TestResolvers } from './../../types.generated';
    export const Test: TestResolvers = {
    /* Implement Test resolver logic here */
        description: () => { /* Test.description resolver is required because Test.description exists but TestMapper.description does not */ }
    };

Describe the solution you'd like Support interface extends.

Describe alternatives you've considered Use class extends instead of interface.

class Base {
  description!: string;
}

export class TestMapper extends Base {
  id!: string;
  name!: string;
}
