Implement infering table model with relations

Prisma API:

```ts
import { Prisma } from '@prisma/client'

// 1: Define a type that includes the relation to `Post`
const userWithPosts = Prisma.validator()({
include: { posts: true },
})

// 2: Define a type that only contains a subset of the scalar fields
const userPersonalData = Prisma.validator()({
select: { email: true, name: true },
})

// 3: This type will include a user and all their posts
type UserWithPosts = Prisma.UserGetPayload
```
