Unable to clear fields using the local API

To Reproduce

Passing undefined

1. Attempt to clear a field like so:
   
2. The code remains the same within the DB (here I'm assuming Payload doesn't know that the data.code key was passed intentionally)

---

Passing null

1. Attempt to clear a field like so:
   
2. null is not allowed by the TS definitions

---

The current workaround is to pass an "empty" but not properly cleared value

Suggestions
I think usage of the in operator or hasOwnProperty could help here to allow passing undefined... BUT this would be a breaking change destroying many peoples' data. So perhaps payload.update's data arg needs to extend the generated-types and allow a magic value to clear the field?

Such as

await req.payload.update({
  collection: 'coll',
  id: someId,
  data: {
    fieldToClear: 'DELETE_THIS_FIELD'
  }
});

Describe the Bug

As far as I know, there is no way to properly clear or delete a field using the local API

Payload Version

1.10.1

Hey @allannnc — your workaround of passing an empty string to the code field is the appropriate way to clear the field's data as of now, but we should build a way to "unset" fields via passing undefined.

This is a new feature and we will add it to our roadmap for sure.

Thanks for bringing this up!
