chore!: simplify api handler (#6910)

Removes PayloadRequestWithData in favour of just PayloadRequest with
optional types for `data` and `locale`

`addDataAndFileToRequest` and `addLocalesToRequestFromData` now takes in
a single argument instead of an object

```ts
// before
await addDataAndFileToRequest({ request: req })
addLocalesToRequestFromData({ request: req })

// current
await addDataAndFileToRequest(req)
addLocalesToRequestFromData(req)
```
