Sasha 23f1ed4a48 feat(db-postgres, db-sqlite): drizzle schema generation (#9953) ...

This PR allows to have full type safety on `payload.drizzle` with a
single command
```sh
pnpm payload generate:db-schema
```
Which generates TypeScript code with Drizzle declarations based on the
current database schema.

Example of generated file with the website template:

We also now proxy drizzle package the same way we do for Lexical so you
don't have to install it (and you shouldn't because you may have version
mismatch).
Instead, you can import from Drizzle like this:
```ts
import {
  pgTable,
  index,
  foreignKey,
  integer,
  text,
  varchar,
  jsonb,
  boolean,
  numeric,
  serial,
  timestamp,
  uniqueIndex,
  pgEnum,
} from '@payloadcms/db-postgres/drizzle/pg-core'
import { sql } from '@payloadcms/db-postgres/drizzle'
import { relations } from '@payloadcms/db-postgres/drizzle/relations'
```


Fixes https://github.com/payloadcms/payload/discussions/4318

In the future we can also support types generation for mongoose / raw
mongodb results.
