Expose native types mapping to DMMF

[unlight]

Problem

We have model with defined native type

model Post {
  id         Int    @id
  title      String @db.VarChar(200)
}

Custom generators may want to use this additional information:

• varchar
• 200 (limit)

But this information is missing, checked node_modules/.prisma/client/index.js @ dmmfString

Suggested solution

Expose db field attributes data/info to DMMF.

I am closing this as we now have an issue at #10252 with active discussion about this. Thanks for creating it.
