feat(query-engine): use @map'd values of enum in query input and output

[jkomyno]

This PR contributes to prisma/prisma#8446.
This PR introduces a breaking change, let's wait for Prisma 6.

With this PR:

• The following schema is now invalid:

  datasource db {
    provider  = "postgresql"
    url       = env("TEST_POSTGRES_URI")
  }
  
  enum FormLanguage {
    EN_US     @map("en/us")
    IT_IT     @map("it/it")
    EN_US_DUP @map("en/us")
  
    @@map("form_language")
  }
  
  model Form {
    id        String       @id @default(cuid())
    language  FormLanguage
  }

Could you please add some tests where you pass a mapped value in a query (or point me to the existing tests)? I assume GraphQL protocol will probably break for enums with numeric values or special characters like / in your languages example.

Right, I've added the new enum_type_mapped test suite in b6ced1e. Locally, I've tested it successfully with Postgres 14.

Updates after some investigation with @aqrln:

• Currently, this fails:

  model User {
    id       Int        @id @default(autoincrement())
    enumUsed PaymentProvider @map("field_mapping") @default(Offline)
  }
  
  enum PaymentProvider {
    MixplatSMS    @map("mixplat/sms")
    InternalToken @map("internal/token")
    Offline       @map("offline")
  
    @@map("payment_provider")
  }

• There are possibly other failing cases.
• Due to this, such breaking change won't be released in Prisma 6.0.0, unfortunately
