[FEATURE]: Ability to generate database typescript type file based on schemas

### Describe what you want

- When using drizzle in a standalone backend, we need database types on the front end to be type-safe.
- InferModel does not work for separate frontend and backend.
- If we can have a utility function something like `drizzle-kit generate:types` which generates a typescript file with database types based on schemas, that will be great because otherwise we have to write these types manually and we can make mistakes in doing so.
- This is inspired by Supabase types generation functionality
