Implement the type version of Object.fromEntries

For example:

typescript
interface Model {
  name: string;
  age: number;
  locations: string[] | null;
}

type ModelEntries = ['name', string] | ['age', number] | ['locations', string[] | null];

type result = ObjectFromEntries<ModelEntries> // expected to be Model
