Add more metadata to Ash.NotLoaded and Ash.NotSelected.

[jimsynz]

We should include extra fields like resource and anything else you can think of to the NotLoaded and NotSelected structs.

[zachdaniel]

We should also set a custom inspect opt when inspecting a resource that hides this when inspecting field values.

i.e

inspect(record)

%Resource{
  field: %Ash.NotLoaded{type: :calculation}
}

inspect(record.field)
%Ash.NotLoaded{type: :calculation, name: :field, resource: Resource}

Hi @zachdaniel I'd like to work on this issue, but I see here you already fixed it in NotLoaded struct. Should I fix it as well for the other struct or you're already on it?

[zachdaniel]

We're actually not going to use NotSelected in 3.0, it will all be NotLoaded, but I think we still want to add the resource key, and implement the inspect logic I mentioned, so there is still work to be done. I'd suggest working against the 3.0 branch for this change.

[m-rwash]

Alright, well noted, will work against 3.0 then

It looks like this might be harder than expected because we don't currently implement the inspect protocol, its the underlying ecto schema.
