perf(db-postgres): simplify db.updateOne to a single DB call with if the passed data doesn't include nested fields (#13060)

In case, if `payload.db.updateOne` received simple data, meaning no:
* Arrays / Blocks
* Localized Fields
* `hasMany: true` text / select / number / relationship fields
* relationship fields with `relationTo` as an array

This PR simplifies the logic to a single SQL `set` call. No any extra
(useless) steps with rewriting all the arrays / blocks / localized
tables even if there were no any changes to them. However, it's good to
note that `payload.update` (not `payload.db.updateOne`) as for now
passes all the previous data as well, so this change won't have any
effect unless you're using `payload.db.updateOne` directly (or for our
internal logic that uses it), in the future a separate PR with
optimization for `payload.update` as well may be implemented.
